Karlheinz Hill, Cognis, Germany<br />

Natural fats <strong>and</strong> oils, carbohydrates <strong>and</strong> proteins are key raw materials <strong>for</strong> the chemical<br />
industry using renewable resources. Although in general, biom<strong>as</strong>s is available in large<br />
amounts (e.g. cellulose), the annual producti<strong>on</strong> volumes of selected biob<strong>as</strong>ed commodities<br />
are still small compared to coal or crude oil.<br />
Annual producti<strong>on</strong> of commodities worldwide (2004, milli<strong>on</strong> t<strong>on</strong>s) a<br />

c) vegetable <strong>and</strong> animal b<strong>as</strong>ed; d) <strong>as</strong> SKE (1 kg SKE = 0,984 kg bituminous coal)<br />
Until now, availability <strong>and</strong> use w<strong>as</strong> quite balanced <strong>and</strong> the quantities could be adjusted<br />
according to different dem<strong>and</strong>s. For example, in the c<strong>as</strong>e of natural oils <strong>and</strong> fats, the<br />
producti<strong>on</strong> volume w<strong>as</strong> steadily incre<strong>as</strong>ed from 30 milli<strong>on</strong> t<strong>on</strong>s in 1960 to 131 milli<strong>on</strong> t<strong>on</strong>s<br />
in 2004. Most of it w<strong>as</strong> used <strong>for</strong> food (81% in 2004), a minor amount <strong>for</strong> animal feed (6% in<br />
2004) <strong>and</strong> chemistry (10% in 2004). However, what we have observed <strong>for</strong> some time is a<br />
shift towards an incre<strong>as</strong>ing use of renewable raw materials <strong>for</strong> bioenergy <strong>and</strong> biofuels. In<br />
the c<strong>as</strong>e of natural vegetable oils, the expected share <strong>for</strong> energy is estimated to grow to<br />
15% (!) of the total annual capacity in 2012 compared to 3% in 2004. This is <strong>on</strong>e<br />
c<strong>on</strong>sequence of political me<strong>as</strong>ures such <strong>as</strong> the European Biofuel Directive 2003/30/EC.<br />
Biodiesel producti<strong>on</strong> volumes were exp<strong>and</strong>ed significantly in the recent p<strong>as</strong>t <strong>and</strong> this trend<br />
is expected to c<strong>on</strong>tinue in Europe <strong>and</strong> other regi<strong>on</strong>s such <strong>as</strong> South E<strong>as</strong>t Asia, South<br />
America <strong>and</strong> India, with a further incre<strong>as</strong>e in producti<strong>on</strong> capacities <strong>for</strong>ec<strong>as</strong>ted at le<strong>as</strong>t <strong>for</strong><br />
the next 5-10 years.<br />
When the so-called 2nd generati<strong>on</strong> products, such <strong>as</strong> sundiesel or biom<strong>as</strong>s-to-liquid fuels,<br />
are ready to be launched <strong>on</strong> the market, the dem<strong>and</strong> <strong>on</strong> fats <strong>and</strong> oils <strong>for</strong> biofuels might<br />
decre<strong>as</strong>e again. These new technologies are definitely needed <strong>as</strong>suming that even with<br />
incre<strong>as</strong>ing producti<strong>on</strong> volumes <strong>for</strong> fats <strong>and</strong> oils, the future bioenergy <strong>and</strong> biofuel dem<strong>and</strong><br />
cannot be satisfied by this source al<strong>on</strong>e.<br />
In the meantime, the high dem<strong>and</strong>s <strong>for</strong> biodiesel, still further stimulated by subsidies, will<br />
create str<strong>on</strong>g competiti<strong>on</strong> with the established uses <strong>for</strong> vegetable oils <strong>for</strong> nutriti<strong>on</strong> <strong>and</strong> also<br />
<strong>for</strong> the chemical industry (oleochemistry). A very similar situati<strong>on</strong> is being observed in the<br />
c<strong>as</strong>e of bioethanol from carbohydrates <strong>and</strong>/or sugar. The competiti<strong>on</strong> between the use of<br />
agricultural products <strong>for</strong> nutriti<strong>on</strong> <strong>and</strong> energy is <strong>on</strong>e of the re<strong>as</strong><strong>on</strong>s why market prices of<br />
such agricultural commodities are recently subject of extremely high volatility. Other<br />
re<strong>as</strong><strong>on</strong>s are the incre<strong>as</strong>ing dem<strong>and</strong> <strong>for</strong> food in various regi<strong>on</strong>s of the earth, crop yield, <strong>and</strong><br />
financial speculati<strong>on</strong>s by investment funds.<br />
The use of renewable resources is <strong>on</strong>ly <strong>on</strong>e important part of the future "green" strategy in<br />
industry. What must also be c<strong>on</strong>sidered are sustainability practices across the entire value<br />
chain. This strategy is already applied to palm oil. It is the first time an expert group (The<br />
Round Table of Sustainable Palm Oil, RSPO) involving all participants in the industrial<br />
agricultural commodity value chain h<strong>as</strong> defined what sustainable agriculture really should<br />
mean. The challenging goal to develop, implement <strong>and</strong> verify credible global st<strong>and</strong>ards <strong>for</strong><br />
sustainable palm oil products h<strong>as</strong> finally been achieved. The principles <strong>and</strong> criteria <strong>for</strong><br />
sustainable palm oil are in the implementati<strong>on</strong> process <strong>and</strong> this year the first products are<br />
available according to the st<strong>and</strong>ards. Cognis w<strong>as</strong> the first chemical supplier in membership<br />
<strong>and</strong> is until today <strong>on</strong>e of the few. Its expertise in natural raw materials enables Cognis to<br />
develop c<strong>on</strong>cepts with its customers <strong>on</strong> how to make renewable raw materials sustainable<br />
<strong>as</strong> almost all of its raw materials from the palm tree are being sourced from RSPO<br />
members.

Carb<strong>on</strong>ylati<strong>on</strong> <strong>as</strong> a route to chemicals from biom<strong>as</strong>s<br />

As oil stocks dwindle <strong>and</strong> become incre<strong>as</strong>ingly expensive, it will become essential to<br />
develop routes to chemicals starting from feedstocks that can be derived from plant<br />
sources. One interesting group of chemicals is the diesters. Especially desirable are the<br />
alpha-omega diesters since they are used in a wide variety of polyesters <strong>for</strong> use in pl<strong>as</strong>tic<br />
bottles, synthetic carpets <strong>and</strong> speciality pl<strong>as</strong>tics. We have been developing a range of<br />
palladium b<strong>as</strong>ed catalysts that can <strong>for</strong>m alpha-omega diesters from unsaturated esters by<br />
methoxycarb<strong>on</strong>ylati<strong>on</strong> reacti<strong>on</strong>s. When these catalysts are applied to methyl oleate,<br />
dimethyl 1,19-n<strong>on</strong>adecanedioate is <strong>for</strong>med in high selectivity. This remarkable reacti<strong>on</strong><br />
involves isomerisati<strong>on</strong> of the double b<strong>on</strong>d to the end of the chain <strong>and</strong>, <strong>on</strong>ly when it is there,<br />
is it carb<strong>on</strong>ylated. The same product is <strong>for</strong>med from methyl linoleate <strong>and</strong> methyl linolenate.<br />
Since shorter chain length diesters are often required, the group of W. R. Jacks<strong>on</strong> in<br />
M<strong>on</strong><strong>as</strong>h Australia h<strong>as</strong> coupled this isomerisati<strong>on</strong> carb<strong>on</strong>ylati<strong>on</strong> reacti<strong>on</strong> with metathesis of<br />
the original oil with butene. The metathesis shortens the chain to give an unsaturated ester<br />
which can be isomerised <strong>and</strong> carb<strong>on</strong>lyated to give shorter alpha-omega diesters. We shall<br />
discuss the nature of the catalysts <strong>and</strong> the re<strong>as</strong><strong>on</strong>s <strong>for</strong> their very specific acti<strong>on</strong>s.<br />

Metathesis with oleochemicals: a sustainable match to obtain<br />
m<strong>on</strong>omers <strong>and</strong> polymers from renewable resources<br />
Michael A. R. Meier, University of Applied Sciences OOW, Emden, Germany<br />
michael.meier@fh-oow.de<br />
In ages of depleting fossil reserves <strong>and</strong> incre<strong>as</strong>ing emissi<strong>on</strong> of green house g<strong>as</strong>es it is<br />
obvious that the utilizati<strong>on</strong> of renewable feedstocks is <strong>on</strong>e necessary step towards a<br />
sustainable development of our future. Especially plant derived oils bear a large potential<br />
<strong>for</strong> the substituti<strong>on</strong> of currently used petrochemicals, since a variety of value added<br />
chemical intermediates can be derived from these resources in a straight<strong>for</strong>ward f<strong>as</strong>hi<strong>on</strong><br />
taking full advantage of nature's synthetic potential. Here, new approaches <strong>for</strong> the<br />
synthesis of m<strong>on</strong>omers <strong>as</strong> well <strong>as</strong> polymers from plant oils <strong>as</strong> renewable resources[1] via<br />
olefin metathesis[2,3] will be discussed. As an example, we recently showed that different<br />
chain length α,ω-diester m<strong>on</strong>omers can be obtained from plant oil derived fatty acid esters<br />
via olefin cross-metathesis[4] with methyl acrylate taking advantage of natures "synthetic<br />
pool" of fatty acids with different chain lengths <strong>and</strong> positi<strong>on</strong>s of double b<strong>on</strong>ds.[5]<br />
Similarly, we could show that the cross-metathesis with allyl chloride <strong>and</strong> other functi<strong>on</strong>al<br />
olefins allows <strong>for</strong> the synthesis of α,ω-difuncti<strong>on</strong>al compounds.[6,7] There<strong>for</strong>e, this strategy<br />
offers the possibility to introduce a variety of different functi<strong>on</strong>al groups to the ω -positi<strong>on</strong><br />
of fatty acid derivatives, thus providing valuable starting materials <strong>for</strong> a variety of<br />
polyesters <strong>and</strong> polyamides.<br />
Moreover, acyclic diene metathesis (ADMET), can be used to directly obtain<br />
macromolecules from such starting materials. The ADMET polymerizati<strong>on</strong> [8] of undecyl<br />
undecenoate, <strong>for</strong> instance, led to high molecular weight polyesters.[9] It w<strong>as</strong> possible to<br />
effciently c<strong>on</strong>trol the molecular weight of these materials <strong>and</strong> to prepare telechelics via the<br />
applicati<strong>on</strong> of m<strong>on</strong>o-functi<strong>on</strong>al chain-stoppers.[9] More interestingly, this approach can<br />
also be used to prepare ABA triblock copolymers with c<strong>on</strong>trol of the degree of<br />
polymerizati<strong>on</strong> (DP) of the B block in a single reacti<strong>on</strong> step.[9] Furthermore, if tri-functi<strong>on</strong>al<br />
m<strong>on</strong>omers in combinati<strong>on</strong> with chain stoppers are investigated the synthesis of<br />
hyperbranched polymer architectures with functi<strong>on</strong>al groups in their periphery can be<br />
achieved in a single reacti<strong>on</strong> step.[10]<br />

Lip<strong>as</strong>es <strong>and</strong> related enzymes (ester<strong>as</strong>e, different phospholip<strong>as</strong>es) are currently used <strong>as</strong><br />
biocatalysts in a broad range of lipid modificati<strong>on</strong>s [1]. In this lecture, the identificati<strong>on</strong> of<br />
novel ester<strong>as</strong>es/lip<strong>as</strong>es from the metagenome will be shown highlighting the discovery of<br />
biocatalysts with certain fatty acid chain-length profiles [2]. Furthermore, methods <strong>for</strong> the<br />
identificati<strong>on</strong> <strong>and</strong> immobilizati<strong>on</strong> of desired enzymes using a microtiterplate (MTP) b<strong>as</strong>ed<br />
method [3, 4] will be presented. An example <strong>for</strong> protein engineering deals with a lip<strong>as</strong>e<br />
from Rhizopus oryzae (ROL), which w<strong>as</strong> engineered to incre<strong>as</strong>e its stability toward lipid<br />
oxidati<strong>on</strong> products such <strong>as</strong> aldehydes with the aim of improving its per<strong>for</strong>mance in<br />
oleochemical industries. Key to success w<strong>as</strong> the saturati<strong>on</strong> mutagenesis of selected Lys<br />
<strong>and</strong> His residues combined with a MTP-b<strong>as</strong>ed high-throughput screening of stable variants<br />
[5]. Furthermore, the use of i<strong>on</strong>ic liquids <strong>as</strong> media <strong>for</strong> the synthesis of sugar fatty acid<br />
esters will be covered [6].<br />

Catalytic Functi<strong>on</strong>alisati<strong>on</strong> of Fatty Compounds<br />
Jessica Pérez Gomes, <strong>and</strong> Arno Behr, Chair of Technical Chemistry A, Technical<br />

Every year the chemical industry uses about 250 milli<strong>on</strong> t<strong>on</strong>s of resources <strong>for</strong> the<br />
producti<strong>on</strong> of organic chemicals. Only 20 milli<strong>on</strong>s t<strong>on</strong>s, that means <strong>on</strong>ly 8-10 %, are b<strong>as</strong>ed<br />
<strong>on</strong> renewable resources, especially <strong>on</strong> fat <strong>and</strong> oils. This c<strong>on</strong>tributi<strong>on</strong> gives a short<br />
overview about the numerous possibilities to functi<strong>on</strong>alise fatty compounds via<br />
homogeneous transiti<strong>on</strong> metal catalysis.<br />
Unsaturated fatty compounds c<strong>on</strong>tain <strong>on</strong>e or more C=C-double b<strong>on</strong>ds which can be<br />
e<strong>as</strong>ily functi<strong>on</strong>alised via coordinati<strong>on</strong> to transiti<strong>on</strong> metal complexes [1]. Some important<br />
examples of these functi<strong>on</strong>alisati<strong>on</strong>s are epoxidati<strong>on</strong>s, dihydroxylati<strong>on</strong>s, oxidative<br />
cleavage reacti<strong>on</strong>s, hydrosilylati<strong>on</strong>s [2-3], hydro<strong>for</strong>mylati<strong>on</strong>s [4] <strong>and</strong><br />
hydroaminomethylati<strong>on</strong>s [5]. Thus new carb<strong>on</strong>-oxygen-, carb<strong>on</strong>-silic<strong>on</strong>-, carb<strong>on</strong>-carb<strong>on</strong>-<br />
<strong>and</strong> carb<strong>on</strong>-nitrogen-b<strong>on</strong>ds can be <strong>for</strong>med yielding a broad spectrum of chemical<br />
compounds with new properties <strong>and</strong> new applicati<strong>on</strong>s. Further important examples are the<br />
rhodium-catalysed cooligomerisati<strong>on</strong>s [6-7] or the ruthenium-catalysed metathesis of fatty<br />
compounds with alkenes.<br />
If fats <strong>and</strong> oils are transesterified with methanol glycerol is <strong>for</strong>med <strong>as</strong> an important byproduct<br />
in oleochemistry. A great number of applicati<strong>on</strong>s of glycerol are well known, however,<br />
the raising amounts of glycerol because of the enormous producti<strong>on</strong> of biodiesel can<br />
not be put into the market. There<strong>for</strong>e new reacti<strong>on</strong>s are needed to trans<strong>for</strong>m glycerol into<br />
new products with new markets. Once again, homogeneous catalysis offers interesting<br />
possibilities [8-9]: Via catalytic oxidati<strong>on</strong>s glycerol acid or dihydroxyacet<strong>on</strong>e can be <strong>for</strong>med.<br />
Dehydratisati<strong>on</strong> yields acrolein which is further oxidised to acrylic acid. Further follow-up<br />
products of glycerol are <strong>for</strong> instance propanediols, epichlorohydrine, glycerol dimers or<br />
trimers, glycerol carb<strong>on</strong>ate, glycerol acetals or ketals. Another important group of<br />
chemicals are the glycerol ethers, <strong>for</strong> instance the glycerol tertiary butyl ethers [10] or the<br />
telomers of glycerol [11-14].<br />

Oxidati<strong>on</strong> of tensidic alcohols to their corresp<strong>on</strong>ding carboxylic<br />
acids via Au- <strong>and</strong> AuPt-catalysts<br />

Reducing the use of envir<strong>on</strong>mentally hazardous chemicals in industrial processes plays a<br />
key role in the science of catalysis. Particularly the liquid-ph<strong>as</strong>e oxidati<strong>on</strong> of tensidic<br />
alcohols to the corresp<strong>on</strong>ding carboxylic acids holds a great potential <strong>for</strong> improvement<br />
towards a “greener” process. Currently ether carboxylic acids are either synthesized via<br />
Williams<strong>on</strong>’s ether-synthesis using chloroacetic acid derivatives. Incomplete c<strong>on</strong>versi<strong>on</strong><br />
<strong>and</strong> c<strong>on</strong>sequential excess use of chloroacetic acid lead to impurities (e.g. educt residues<br />
<strong>and</strong> by-products) which accelerate the deteriorati<strong>on</strong> of the acid <strong>and</strong> impair its solubility. Or<br />
they can be produced by oxidising the corresp<strong>on</strong>ding alcohol with dioxygen using<br />
supported Pt- or Pd- catalysts. However, difficulties such <strong>as</strong> metal leaching <strong>and</strong> incomplete<br />
c<strong>on</strong>versi<strong>on</strong> may occur during this process. Our research group is first to develop <strong>and</strong><br />
employ m<strong>on</strong>o- <strong>and</strong> bimetallic Au-catalysts <strong>for</strong> the liquid-ph<strong>as</strong>e oxidati<strong>on</strong> of fatty alcohol<br />
ethoxylates <strong>and</strong> related model compounds, i.e. alkyl ethoxylates <strong>and</strong> ethoxylates, to their<br />
corresp<strong>on</strong>ding carboxylic acid.<br />
Several preparati<strong>on</strong> methods, catalyst supports <strong>and</strong> Au-Pt-ratios (<strong>for</strong> bimetallic catalysts)<br />
were screened. For all model compounds m<strong>on</strong>ometallic Au-catalysts featured a selectivity<br />
of 100 % to the carboxylic acid. Maintaining total selectivity, the activity could be incre<strong>as</strong>ed<br />
significantly by using a bimetallic Au-Pt-catalyst with a gold: platinum ratio of 90:10. Thus,<br />
<strong>for</strong> comparable reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s our catalyst w<strong>as</strong> ten times <strong>as</strong> active <strong>as</strong> a Pt-catalyst.<br />
The experiments were carried out at elevated pressures (5-30 bar) in thermostatted<br />
stainless steel autoclaves at c<strong>on</strong>stant pH (9 -11). Variati<strong>on</strong> of reacti<strong>on</strong> parameters <strong>and</strong><br />
kinetic studies revealed a dependency of the activity <strong>on</strong> temperature (80 – 130 °C), oxygen<br />
pressure, pH-value <strong>and</strong> educt c<strong>on</strong>centrati<strong>on</strong> (5 – 80 %) – all of which do not affect the<br />
selectivity.<br />
The reacti<strong>on</strong> mechanism should be identical <strong>for</strong> all model compounds. However, during<br />
the oxidati<strong>on</strong> of certain fatty alcohol ethoxylates with m<strong>on</strong>ometallic Au-catalysts<br />
intermediate metal leaching occurs. This phenomen<strong>on</strong> does not arise with the other two<br />
model compounds. Preliminary results suggest that metal leaching can be reduced<br />
c<strong>on</strong>siderably by employing bimetallic catalysts with a proper Au-Pt-ratio.<br />

Phytomining of plant enzymes <strong>for</strong> biotechnological use of fats <strong>and</strong> oils<br />

Human history is closely linked to the use of plants <strong>as</strong> valuable sources <strong>for</strong> nutriti<strong>on</strong>,<br />
commodities <strong>and</strong> energy <strong>as</strong> well <strong>as</strong> a multitude of raw materials, such <strong>as</strong> fats, oils <strong>and</strong><br />
natural polymers like cellulose or starch. However, <strong>on</strong>ly recently have we come to see<br />
plants <strong>as</strong> a cornerst<strong>on</strong>e of sustainable industry by exploiting lead structures <strong>and</strong><br />
biosynthetic pathways <strong>for</strong> the modificati<strong>on</strong> of plant derived, renewable resources.<br />
Plant derived fats <strong>and</strong> oils are already used by the Chemical Industry <strong>as</strong> renewable<br />
feedstock <strong>and</strong> unsaturated fatty acids, often found in plant oils, represent well suited raw<br />
materials <strong>for</strong> the producti<strong>on</strong> of polymers, pl<strong>as</strong>ticizer <strong>and</strong> lubricants. Doubtlessly, the wealth<br />
of plant biosynthetic pathways makes plants an attractive source <strong>for</strong> f<strong>as</strong>cinating new<br />
enzymes <strong>for</strong> fat <strong>and</strong> oil modificati<strong>on</strong> <strong>and</strong> biotechnological applicati<strong>on</strong>s. Use of plant<br />
enzyme <strong>and</strong> compounds in industrial biotechnology offers new means to address/reach<br />
energy savings <strong>and</strong> incre<strong>as</strong>es of efficiency <strong>and</strong> sustainability by reducing the number of<br />
steps in processing chains, <strong>for</strong> example.<br />
Phytowelt GreenTechnologies GmbH excels enzyme discovery via phytomining, a<br />
combinatory high c<strong>on</strong>tent approach. Our four step integrative approach aims to incre<strong>as</strong>e<br />
the efficiency of current producti<strong>on</strong> processes, e.g. by complementing microbial producti<strong>on</strong><br />
lines with a suitable gene, or implementing completely new <strong>and</strong> innovative fermentati<strong>on</strong><br />
processes. Phytowelt’s approach unlocks the huge potential of plant biodiversity.<br />
Phytowelt’s presentati<strong>on</strong> will introduce its phytomining plat<strong>for</strong>m <strong>and</strong> the power of (plant)<br />
enzymes. Examples <strong>for</strong> the applicati<strong>on</strong> of plant enzymes will be given.<br />

Rati<strong>on</strong>al design of solid catalysts <strong>for</strong> selective glycerol activati<strong>on</strong>s<br />

joel.barrault@univ-poitiers.fr<br />
With the aim of finding soluti<strong>on</strong>s to the disappearance of fossil raw materials,<br />
scientists focused their attenti<strong>on</strong> towards the use of natural products. However, these<br />
products are in most c<strong>as</strong>es polyfuncti<strong>on</strong>al <strong>and</strong> their trans<strong>for</strong>mati<strong>on</strong>s require the close<br />
c<strong>on</strong>trol of the chemio- <strong>and</strong>/or regio- <strong>and</strong>/or enantioselectivity of processes. To overcome<br />
these problems, catalysis w<strong>as</strong> expected to play a pivotal role by offering to chemists useful<br />
tools <strong>for</strong> per<strong>for</strong>ming selective trans<strong>for</strong>mati<strong>on</strong>s of renewables to high added value<br />
chemicals. Recent studies clearly showed that inorganic solid supports can directly <strong>and</strong><br />
positively impact <strong>on</strong> the reacti<strong>on</strong> selectivity.<br />
Development of new catalysts with c<strong>on</strong>trolled distributi<strong>on</strong> of active sites is probably<br />
<strong>on</strong>e of the most f<strong>as</strong>cinating examples. But a c<strong>on</strong>trol of the hydrophilicity of catalytic<br />
surfaces is also an important parameter. Playing with the hydrophilic properties of the<br />
catalyst surface, we found that it w<strong>as</strong> possible to limit a lot of sec<strong>on</strong>dary reacti<strong>on</strong>s allowing<br />
us to trans<strong>for</strong>m glycerol with yields <strong>and</strong> selectivities higher than those obtained with<br />
homogeneous <strong>and</strong> usual solid acid or b<strong>as</strong>ic catalysts.

Acid-catalysed rearrangement of fatty epoxides: perspectives in<br />
applicati<strong>on</strong> of acid sap<strong>on</strong>ites<br />

The ring opening of epoxidized fatty acid derivatives is a valuable trans<strong>for</strong>mati<strong>on</strong> <strong>for</strong> the<br />
producti<strong>on</strong> of compounds functi<strong>on</strong>alized <strong>on</strong> the alkyl chain. Rearranged epoxides could<br />
find applicati<strong>on</strong>s <strong>as</strong> precursors of biopolymers, lubricants, polyurethane foams <strong>and</strong> c<strong>as</strong>ting<br />
resins.<br />
A two-step process, starting from fatty acid methyl esters <strong>and</strong> b<strong>as</strong>ed uniquely <strong>on</strong><br />
heterogeneous <strong>and</strong> e<strong>as</strong>ily recoverable catalysts, is here proposed. The FAME methyl<br />
oleate is epoxidized in liquid ph<strong>as</strong>e with tert-butylhydroperoxide in batch reactor over Tigrafted<br />
MCM-41. The trans<strong>for</strong>mati<strong>on</strong> is optimized <strong>and</strong> the c<strong>on</strong>versi<strong>on</strong> attains >90% after<br />
24 h, with selectivity >95% to methyl 9,10-epoxystearate. After separati<strong>on</strong> of the organic<br />
product from the solid Ti-catalyst, the ring opening of the epoxidized fatty ester is<br />
per<strong>for</strong>med in the presence of a prot<strong>on</strong>ic acidic sap<strong>on</strong>ite clay, obtained by exchanging a<br />
synthetic Na+ sap<strong>on</strong>ite in aqueous HCl soluti<strong>on</strong>s at different c<strong>on</strong>centrati<strong>on</strong>s. The catalytic<br />
results <strong>for</strong> the nucleophilic additi<strong>on</strong> of methanol to methyl epoxystearate show the good<br />
per<strong>for</strong>mance of different acid sap<strong>on</strong>ites in terms of activity. The sap<strong>on</strong>ite catalysts were<br />
also compared with other widely used heterogeneous systems, such <strong>as</strong> mesoporous<br />
ordered aluminosilicate Al-SBA-15 <strong>and</strong> a prot<strong>on</strong>ic Beta zeolite (H-BEA). Prot<strong>on</strong>ic sap<strong>on</strong>ites<br />
showed better results than H2SO4 too (0.45 mmol g -1 ), the typical industrial catalyst <strong>for</strong> this<br />
reacti<strong>on</strong>.<br />
The best result is obtained over the prot<strong>on</strong>ic sap<strong>on</strong>ite prepared with a mild pretreatment<br />
(i<strong>on</strong> exchange in aq. 0.01 M HCl): with methanol, after 5 min, 90% of the epoxide is readily<br />
c<strong>on</strong>verted into Me-methoxyhydroxystearate <strong>and</strong> Me-oxostearate.<br />

Fatty acids are b<strong>as</strong>is ingredients <strong>for</strong> a wide range of c<strong>on</strong>sumer <strong>and</strong> technical products, <strong>for</strong><br />
which they provide properties <strong>and</strong> benefits not readily or ec<strong>on</strong>omically achieved using<br />
mineral-derived sources.<br />
They can c<strong>on</strong>tribute to the development of a more sustainable, biob<strong>as</strong>ed ec<strong>on</strong>omy –not<br />
<strong>on</strong>ly through their inherent natural b<strong>as</strong>is, but also through the ability of the fatty acid<br />
producers to h<strong>and</strong>le a wide range of technical/n<strong>on</strong>-edible oil <strong>and</strong> fat sources <strong>and</strong> to make<br />
from them high quality, well-defined materials <strong>for</strong> value-added <strong>on</strong>ward applicati<strong>on</strong>.<br />
Furthermore, the natural mixtures can be readily purified <strong>and</strong> separated to yield end<br />
products with precise functi<strong>on</strong>ality <strong>and</strong> properties, distinct from those of the parent<br />

This talk will outline the processing <strong>and</strong> chemistry of fatty acids, <strong>and</strong> illustrate their<br />

Agricultural crops represent a c<strong>on</strong>siderable reservoir of useful <strong>and</strong> low cost raw materials<br />
like fats <strong>and</strong> oils, plant proteins <strong>and</strong> carbohydrates. By selective combinati<strong>on</strong> of their<br />
molecular c<strong>on</strong>stituents (e.g. fatty acids, glycerol, amino acids, m<strong>on</strong>o- <strong>and</strong> disaccharides,<br />
amino sugars etc.) a wide variety of surface active materials can be prepared, all of them -<br />
due to their molecular structures - being potentially highly biodegradable.<br />
Lip<strong>as</strong>es are well established biocatalysts <strong>for</strong> the selective <strong>for</strong>mati<strong>on</strong> of ester <strong>and</strong> amide<br />
b<strong>on</strong>ds <strong>and</strong> thus ideally suited <strong>for</strong> the preparati<strong>on</strong> of combinati<strong>on</strong> products with surface<br />
active properties such <strong>as</strong> partial glycerides, N-acylated amino acids <strong>and</strong> sugar esters. A<br />
comm<strong>on</strong> problem <strong>as</strong>sociated with enzymatic acylati<strong>on</strong>s of hydrophilic materials in<br />
hydrophobic aprotic organic solvents is the low solubility of the above substrates in such<br />
media. C<strong>on</strong>sequently, practical soluti<strong>on</strong>s had to be developed in order to obtain acceptable<br />
yields. Using a) immobilizati<strong>on</strong>s <strong>on</strong> solid supports, b) supersaturated soluti<strong>on</strong>s <strong>and</strong> c)<br />
temporary protecti<strong>on</strong> groups acceptable results were achieved in most c<strong>as</strong>es. In the<br />
lecture examples <strong>for</strong> the preparati<strong>on</strong> of the above product lines will be discussed, this also<br />

We recently discovered that hydroxy carboxylic acids like malic, tartaric <strong>and</strong> citric acid can<br />
be c<strong>on</strong>verted in <strong>on</strong>e step <strong>and</strong> quantitatively into the title compounds by reacting them with<br />
fatty acid chlorides. The title compounds are excellent electrophiles <strong>for</strong> ring opening<br />
reacti<strong>on</strong>s with a broad variety of nucleophiles – also frequently from renewable resources -<br />
such <strong>as</strong> alcohols, carbohydrates, amines, amino acids <strong>and</strong> amino sugars. This way a wide<br />

interesting (useful) surfactants <strong>and</strong>/or emulsifiers <strong>for</strong> applicati<strong>on</strong>s in cosmetics, <strong>as</strong> food<br />

Nature provides in fatty acids a raw material of high synthetic value. Fatty acids are even<br />
numbered carboxylic acids with 12 to 24 carb<strong>on</strong> atoms <strong>and</strong> an unbranched alkyl chain that<br />
bears <strong>on</strong>e to several - mostly Z-c<strong>on</strong>figurated - double b<strong>on</strong>ds <strong>and</strong> hydroxy groups in<br />
distinct positi<strong>on</strong>s.<br />
A variety of efficient synthetic c<strong>on</strong>versi<strong>on</strong>s h<strong>as</strong> been reported <strong>for</strong> fatty acids [1]. These<br />
comprise C,C-b<strong>on</strong>d <strong>for</strong>mati<strong>on</strong>s <strong>and</strong> functi<strong>on</strong>al group interc<strong>on</strong>versi<strong>on</strong>s. There are<br />
substituti<strong>on</strong>s of CH-b<strong>on</strong>ds in ω- <strong>and</strong> ω-1-positi<strong>on</strong>, in allylic positi<strong>on</strong> or adjacent to a<br />
carb<strong>on</strong>yl group. Described are furthermore electrophilic, radical, nucleophilic additi<strong>on</strong>s,<br />
cycloadditi<strong>on</strong>s, metathesis, <strong>for</strong>mati<strong>on</strong> of triple b<strong>on</strong>ds <strong>and</strong> their c<strong>on</strong>versi<strong>on</strong>. Carb<strong>on</strong> atoms<br />
adjacent to the carboxyl group can be subjected to radical coupling <strong>and</strong> additi<strong>on</strong> by way of<br />
electrochemical decarboxylati<strong>on</strong>.<br />
Higher value products have been obtained by us by combining the amphiphilic nature of<br />
the fatty acid with bioactive groups [2], carbohydrates [3], dyes [4], corrosi<strong>on</strong> inhibitors [4],<br />
antioxidants [5] <strong>and</strong> <strong>as</strong> organogels [6] or i<strong>on</strong> channels [7].<br />
Tensides are surface active compounds <strong>for</strong> which the amphiphilic nature of fatty acids<br />
provides excellent prec<strong>on</strong>diti<strong>on</strong>s. For applicati<strong>on</strong>s of domestic oils <strong>as</strong> tensides the<br />
hydrophilic properties of C18 to C22 fatty acids have to be incre<strong>as</strong>ed. We report here <strong>on</strong><br />
Gemini-tensides obtained by attaching two polar groups to the double b<strong>on</strong>d of oleic acid,<br />
erucic acid <strong>and</strong> petroselinic acid [8]. Polar groups are ethoxylates, carbohydrates, sulfates<br />
<strong>and</strong> phosphates.<br />
The tensidic properties of the compounds <strong>as</strong> water solubility, decre<strong>as</strong>e of the surface<br />
tensi<strong>on</strong>, critical micelle c<strong>on</strong>centrati<strong>on</strong>, interfacial tensi<strong>on</strong> <strong>and</strong> foaming behaviour are<br />
reported <strong>and</strong> compared with these from lauric oils.<br />
The 9,10-bis(methylethyleneglycol) adduct to methyl oleate turned out to be an artificial i<strong>on</strong><br />
channel. The activity w<strong>as</strong> determined by me<strong>as</strong>urements of the acid induced fluorescence<br />
decay in vesicles <strong>and</strong> i<strong>on</strong> c<strong>on</strong>ductance of single channels in lipid membranes. The i<strong>on</strong><br />
c<strong>on</strong>ductivity is comparable to this of the natural i<strong>on</strong> channel <strong>for</strong>ming compound:<br />
gramicidine. As gramicidine the synthetic channels exhibit an antibiotic acitivtity against<br />
Gram-positive <strong>and</strong> Gram-negative microorganisms.<br />

During the l<strong>as</strong>t few years modern synthetic methods have been applied extensively to fatty<br />
compounds <strong>for</strong> the selective functi<strong>on</strong>alizati<strong>on</strong> of the C,C-double b<strong>on</strong>d of unsaturated fatty<br />
compounds <strong>and</strong> gave a large number of novel fatty compounds from which interesting<br />
properties are expected.[1] Presently our interest is focused to plant oils c<strong>on</strong>taining<br />
unsaturated fatty acids with a highly reactive hexatriene system such <strong>as</strong> calendula oil <strong>and</strong><br />
tung oil. The latter – obtained from the nuts of the tung oil tree - is a drying oil <strong>and</strong> is used<br />
<strong>for</strong> a number of products including varnish, resins, inks, paints <strong>and</strong> coatings. Similar<br />
properties are expected from calendula oil. Octadec-8,10-trans-12-cis-trienoic acid<br />
(calendic acid) is the main fatty acid (ca. 60%) in the seed oil of calendula officinalis. We<br />
obtained calendic acid esters from the native oil by a simple transesterificati<strong>on</strong> method<br />
using alcohols, i.e. methanol, ethanol or isopropanol <strong>and</strong> sodium methoxide <strong>as</strong> catalyst.<br />
The solvent-free Diels-Alder reacti<strong>on</strong> of methyl calendulate <strong>and</strong> maleic anhydride gave<br />
exclusively <strong>on</strong>e highly functi<strong>on</strong>alized cycloadditi<strong>on</strong> product in 78% yield. The endo-8,12cycloadditi<strong>on</strong><br />
product w<strong>as</strong> <strong>for</strong>med with high regio- <strong>and</strong> stereoselectivity.[2] The reacti<strong>on</strong><br />
can be applied to the native oil <strong>as</strong> well.<br />
In a patent by DSM methyl calendulate is described <strong>as</strong> a very efficient reactive diluent.[3]<br />
In additi<strong>on</strong> to this we obtained even better results <strong>for</strong> ethyl <strong>and</strong> isopropyl calendulate <strong>as</strong><br />
reactive diluent showing low viscosity <strong>and</strong> good drying properties.<br />
In special applicati<strong>on</strong>s e.g. in coating material used in the outskirt area the substituti<strong>on</strong> of<br />
tung oil should be possible by calendula oil.<br />

Crops: A Green Approach toward Self-Assembled Soft Materials<br />

This talk presents novel <strong>and</strong> emerging c<strong>on</strong>cept of generating various <strong>for</strong>ms of soft<br />
materials from renewable resources. In future research, developing soft nanomaterials<br />
from renewable resources (an alternative feedstock) would be f<strong>as</strong>cinating yet dem<strong>and</strong>ing<br />
practice, which will have direct impact <strong>on</strong> industrial applicati<strong>on</strong>s, <strong>and</strong> ec<strong>on</strong>omically viable<br />
alternatives. Our c<strong>on</strong>tinuous ef<strong>for</strong>ts in this area led us to develop new glycolipids from<br />
industrial byproducts such <strong>as</strong> c<strong>as</strong>hew-nut-shell-liquid, which up<strong>on</strong> self-<strong>as</strong>sembly produced<br />
soft nanoarchitectures including lipid nanotubes, twisted/helical nanofibers, low-molecularweight<br />
gels <strong>and</strong> liquid crystals. More recently, we have developed multiple systems b<strong>as</strong>ed<br />
<strong>on</strong> biob<strong>as</strong>ed organic synthesis by chemical/biocatalytic methods <strong>for</strong> functi<strong>on</strong>al<br />
applicati<strong>on</strong>s. We used the ‘chiral pool’ of carbohydrates using the selectivity of enzyme<br />
catalysis yield amphiphilic products from biob<strong>as</strong>ed feedstock including amygdalin,<br />
trehalose <strong>and</strong> vitamin-C. Amygdalin amphiphiles showed unique gelati<strong>on</strong> behaviour in a<br />
broad range of solvents such <strong>as</strong> n<strong>on</strong>-polar hexanes to polar aqueous soluti<strong>on</strong>s.<br />
Importantly, an enzyme triggered drug-delivery model <strong>for</strong> hydrophobic drugs w<strong>as</strong><br />
dem<strong>on</strong>strated by using these supramolecularly <strong>as</strong>sembled hydrogels. Intriguingly, by<br />
combining biocatalysis, with principles of green <strong>and</strong> supramolecular chemistry, we<br />
developed building blocks-to-<strong>as</strong>sembled materials. Also address the advances that have<br />
led to the underst<strong>and</strong>ing of chiral behaviour <strong>and</strong> the subsequent ability to c<strong>on</strong>trol the<br />
structure of glycolipid nanostructures, <strong>and</strong> the resulting impact of this <strong>on</strong> future material<br />
applicati<strong>on</strong>s. These results will lead to efficient molecular design of supramolecular<br />
architectures <strong>and</strong> nanomaterials from underutilized plant/crop-b<strong>as</strong>ed renewable<br />
feedstocks.<br />

Exploiting vegetable oils <strong>for</strong> the delivery of hydrophilic drugs<br />

The use of oils <strong>and</strong> fats <strong>as</strong> pharmaceuticals dates back to biblical times. Through the ages,<br />
the science <strong>and</strong> technology of fats <strong>and</strong> oils <strong>and</strong> their chemical derivatives h<strong>as</strong> progressed<br />
from traditi<strong>on</strong>al products to high-value applicati<strong>on</strong>s, including lipid-b<strong>as</strong>ed drug delivery<br />
systems. Lipid-b<strong>as</strong>ed drug delivery is c<strong>on</strong>sidered a viable strategy <strong>for</strong> incre<strong>as</strong>ing drug<br />
efficacy <strong>and</strong> reducing drug toxicity. Liposomes are am<strong>on</strong>g the lipid-b<strong>as</strong>ed delivery systems<br />
which are extensively studied but targeting them to specific tissues, is still problematic.<br />
Toward overcoming the limitati<strong>on</strong>s of the cl<strong>as</strong>sical liposomes (made of phospholipids that<br />
<strong>for</strong>m bilayer membrane), we are developing lipid-b<strong>as</strong>ed m<strong>on</strong>olayer cati<strong>on</strong>ic vesicles made<br />
of bolaamphiphilic compounds c<strong>on</strong>taining two hydrophilic head groups at each end of an<br />
alkyl chain. The c<strong>on</strong>cept is to mimic the high chemical <strong>and</strong> physical stability of<br />
archaebacteria membranes, which is made from bolaamphiphiles. Since it is hard to<br />
isolate bolaamphiphiles from araebacteria <strong>and</strong> their synthesis is also difficult, we took a<br />
different approach - synthesizing novel bolaamphiphiles designed to <strong>for</strong>m stable nano<br />
vesicles from functi<strong>on</strong>al vegetable oils that are excellent renewable resources <strong>for</strong> the<br />
chemical industry. Vern<strong>on</strong>ia oil, a naturally epoxidized triglyceride obtained from the seeds<br />
of Vern<strong>on</strong>ia galamensis, is probably the most promising of these functi<strong>on</strong>al oils with<br />
respect of a facile synthesis of functi<strong>on</strong>alized bolaamphiphiles. Yet, other natural fatty<br />
acids, or oleochemicals derived from them, can also serve <strong>as</strong> a starting material <strong>for</strong> the<br />
synthesis of such bolaamphiphiles.<br />
Here we describe the synthesis of a series of symmetrical <strong>and</strong> <strong>as</strong>ymmetrical<br />
bola¬amphiphilic compounds that <strong>for</strong>m vesicles with unique properties needed <strong>for</strong> targeted<br />
drug delivery. When the head groups are substrates <strong>for</strong> an enzyme with high activity at the<br />
target tissue, the vesicular structure will be disrupted <strong>and</strong> the vesicles will rele<strong>as</strong>e the<br />
encapsulated drug primarily there. C<strong>on</strong>jugates between vern<strong>on</strong>ia moiety <strong>and</strong> polyethylene<br />
glycol (PEG) or chitosan, were also prepared <strong>and</strong> incorporated into the membrane of the<br />
cati<strong>on</strong>ic vesicles in order to prol<strong>on</strong>ged the circulatory survival of the vesicles <strong>and</strong> to<br />
incre<strong>as</strong>e penetrability through the blood-brain barrier (BBB) <strong>and</strong> the intestinal wall.<br />
Efficacy of these vesicles <strong>as</strong> a drug delivery system w<strong>as</strong> dem<strong>on</strong>strated with encapsulated<br />
enkephalin (ENK) that w<strong>as</strong> shown to induce analgesia where<strong>as</strong> n<strong>on</strong>-encapsulated ENK did<br />
not cause any analgesic effect.<br />
In summary, we have dem<strong>on</strong>strated that cati<strong>on</strong>ic vesicles with m<strong>on</strong>olayer membrane<br />
made from novel bolaamphiphiles with head groups that are hydrolyzed by specific<br />
enzyme with high activity at the target tissue c<strong>on</strong>stitute an efficient targeted drug delivery<br />
system.

The usage of renewable resources h<strong>as</strong> a l<strong>on</strong>g traditi<strong>on</strong> in chemical industry. Depleti<strong>on</strong> of<br />
fossil resources, climate change <strong>and</strong> CO2 footprint discussi<strong>on</strong>s al<strong>on</strong>g with technical<br />
breakthroughs in the p<strong>as</strong>t decade to c<strong>on</strong>vert renewable resources more efficiently have led<br />
to many initiatives in industry <strong>and</strong> academia <strong>as</strong> well <strong>as</strong> to further explore opportunities of<br />
renewable resources. [1]<br />
In this presentati<strong>on</strong> an overview will be given how BayerMaterialScience approaches the<br />
area of renewable resources <strong>and</strong> two examples will be discussed in more detail relating to<br />
the polyurethane industry: (1) The use of vegetable oils <strong>for</strong> the manufacture of polyetherpolyols<br />
with a renewable c<strong>on</strong>tent ranging from 40-70 % by weight <strong>and</strong> (2) the use of<br />
succinic acid in polyester-polyols <strong>and</strong> <strong>as</strong> a C4 plat<strong>for</strong>m chemical. [2]<br />

Novel bio-b<strong>as</strong>ed polyols were prepared from hydro<strong>for</strong>mylated oleic acid (9-hydroxymethyloctadecanoic<br />
acid) methyl esters <strong>and</strong> trimethylol propane by transesterificati<strong>on</strong>.<br />
Hydro<strong>for</strong>mylati<strong>on</strong> produces primary hydroxyls, which allow relatively lower<br />
transesterificati<strong>on</strong> temperatures <strong>and</strong> better yields than hydroxyfatty acids with sec<strong>on</strong>dary<br />
OH groups. These n<strong>on</strong>-crystallizing polyols (HFME) have no double b<strong>on</strong>ds <strong>and</strong> their<br />
viscosities are acceptable. Polyurethane el<strong>as</strong>tomers prepared by reacting these polyols<br />
with diphenylmethane diisocyanate (MDI) had gl<strong>as</strong>s transiti<strong>on</strong>s temperatures from -33 to -<br />
56 o C, depending <strong>on</strong> the molecular weight of the triols. Tensile strength <strong>and</strong> Shore A<br />
hardness were higher <strong>and</strong> el<strong>on</strong>gati<strong>on</strong>, swelling <strong>and</strong> sol fracti<strong>on</strong> lower than those of<br />
corresp<strong>on</strong>ding networks from polyricinoleic polyols. The pl<strong>as</strong>ticizing effect of l<strong>on</strong>ger<br />
dangling chains in HFME-b<strong>as</strong>ed polyurethanes were matched to a certain degree by the<br />
presence of double b<strong>on</strong>ds in the polyricinoleic polyols, effectively resulting in similar gl<strong>as</strong>s<br />
transiti<strong>on</strong>s.

New approaches to polymers <strong>and</strong> composites from plant oils<br />
Selim Küsefoglu, Bogazici University Chemistry Department, Istanbul, Turkey<br />
kusef@boun.edu.tr<br />
Almost all commercially successful polymers <strong>and</strong> pl<strong>as</strong>tics are now synthesized from<br />
petroleum b<strong>as</strong>ed raw materials. Manufacture of useful polymers from plant oils would<br />
present a number of advantages such <strong>as</strong> the renewability of the raw materials, f<strong>as</strong>t<br />
biodegradability of the polymers <strong>and</strong> cheaper prices. Synthesis of polymers from plant oils<br />
is not new: ancient Egyptians used flax oil to protect the wood in their ships. However<br />
synthesis of rigid, load bearing polymers that are suitable <strong>for</strong> fiber rein<strong>for</strong>cement is a new<br />
<strong>and</strong> very active research field.<br />
When an organic chemist looks at a triglyceride the double b<strong>on</strong>ds, the allylic<br />
positi<strong>on</strong>s, the carb<strong>on</strong>yl group <strong>and</strong> the alfa positi<strong>on</strong> to the carb<strong>on</strong>yl group are noticed <strong>as</strong> the<br />
<strong>on</strong>ly useful positi<strong>on</strong>s <strong>for</strong> derivatizati<strong>on</strong>. So the t<strong>as</strong>k of the polymer chemist is to synthesize<br />
new m<strong>on</strong>omers from plant oils using these functi<strong>on</strong>al groups. The following are some<br />
examples from our ef<strong>for</strong>ts in this field.<br />
Epoxidati<strong>on</strong> of the soybean oil double b<strong>on</strong>ds followed by opening of the epoxy ring<br />
with acrylic acid gave acrylated epoxidized soybean oil (AESO) which is a plant oil b<strong>as</strong>ed<br />
analog of vinyl ester resins. When this m<strong>on</strong>omer is mixed with styrene reactive diluent, a<br />
liquid molding resin is obtained which can be rein<strong>for</strong>ced with gl<strong>as</strong>s fiber <strong>and</strong> can be cured<br />
free radically to give laminates with a tensile strength of 450Mpa (1)<br />

Plant oils can be brominated at the allylic positi<strong>on</strong>s e<strong>as</strong>ily . Reacti<strong>on</strong> of allylic bromide with<br />
silver isocyanate gives the isocyanate substituted triglyceride. This molecule can be e<strong>as</strong>ily<br />
c<strong>on</strong>verted to polyurethanes with various diols <strong>and</strong> polyols <strong>and</strong> particularly, with hydroxyl<br />
bearing oils such <strong>as</strong> c<strong>as</strong>tor oil. Thus the first example of a polyurethane where both of the<br />
m<strong>on</strong>omers are plant oil b<strong>as</strong>ed are obtained. The polymer is suitable <strong>for</strong> the producti<strong>on</strong> of<br />
flexible foams. (2)<br />
Acrylated epoxidized soybean oil can be reacted with furylamine in a Michael reacti<strong>on</strong>.<br />
When the amine is the limiting reagent a desired fracti<strong>on</strong> of the acrylate groups can be<br />
preserved <strong>for</strong> future manipulati<strong>on</strong>s. The resulting amine can be e<strong>as</strong>ily quaternized with<br />
methyl iodide <strong>and</strong> the product turns out to be an excellent exfoliating agent <strong>for</strong><br />
m<strong>on</strong>tmorill<strong>on</strong>ite clay. XRD analysis indicated an incre<strong>as</strong>e in intergallery distance from 12<br />

Our work in this exciting field h<strong>as</strong> so far produced approximately 140 new plant oil b<strong>as</strong>ed<br />
polymers am<strong>on</strong>g which 12 are promising in terms of mechanical properties <strong>and</strong> e<strong>as</strong>e of<br />
synthesis. Newer strategies wherby the oil b<strong>as</strong>ed m<strong>on</strong>omer is grafted <strong>on</strong>to an existing high<br />

clear from a social, envir<strong>on</strong>mental <strong>and</strong> energy st<strong>and</strong>point, with the incre<strong>as</strong>ing emph<strong>as</strong>is <strong>on</strong><br />
issues c<strong>on</strong>cerning w<strong>as</strong>te disposal <strong>and</strong> depleti<strong>on</strong> of n<strong>on</strong> renewable resources. Vegetable<br />
oils are <strong>on</strong>e of the cheapest <strong>and</strong> most abundant, annually renewable natural resources<br />
available in large quantities from various oilseeds <strong>and</strong> are now being used in an incre<strong>as</strong>ing<br />
number of industrial applicati<strong>on</strong>s. In recent years, extensive work h<strong>as</strong> been d<strong>on</strong>e to<br />
develop polymers from triglycerides of fatty acids <strong>as</strong> the main comp<strong>on</strong>ent.<br />
The purpose of our research is to develop new biob<strong>as</strong>ed thermosetting polymers from<br />
vegetable oils <strong>as</strong> renewable resources. Vegetable oils are triglycerides of different fatty<br />
acids with varying degrees of unsaturati<strong>on</strong>. Although they possess double b<strong>on</strong>ds, it is<br />
generally c<strong>on</strong>sidered difficult to polymerise vegetable oils themselves due to its low<br />
reactivity. Our research focuses <strong>on</strong> improving the physical properties of triglyceride b<strong>as</strong>ed<br />
materials, because they dem<strong>on</strong>strated low molecular weights <strong>and</strong> light crosslinking,<br />
incapable of displaying the necessary rigidity <strong>and</strong> strength required <strong>for</strong> structural<br />
applicati<strong>on</strong>s by themselves. In this way, polymers ranging from soft rubbers to hard<br />
pl<strong>as</strong>tics can be obtained by cati<strong>on</strong>ic copolymerisati<strong>on</strong> with styrene <strong>and</strong> divinylbenzene.<br />
Like other organic polymeric materials, the flammability of vegetable oil b<strong>as</strong>ed materials is<br />
a shortcoming in some applicati<strong>on</strong>s. The c<strong>on</strong>cept of sustainable development requires fire<br />
retardant technologies to be developed which have minimum impact <strong>on</strong> health <strong>and</strong> the<br />
envir<strong>on</strong>ment through the life cycle of the fire-retardant material; that is to say, its synthesis,<br />
fabricati<strong>on</strong>, use, recycling <strong>and</strong> disposal. To further extend the applicati<strong>on</strong> of renewable<br />
resources <strong>and</strong> to obtain flame retardant polymers, we synthesized polymers from<br />
vegetable oils, styrene, divinylbenzene <strong>and</strong> silic<strong>on</strong>, phosphorus or bor<strong>on</strong>-c<strong>on</strong>taining<br />
reactive modifiers.<br />
The presence of double b<strong>on</strong>ds makes possible to attach some functi<strong>on</strong>al groups through<br />
chemical modificati<strong>on</strong> <strong>and</strong> we described various chemical pathways <strong>for</strong> functi<strong>on</strong>alising<br />
triglycerides <strong>and</strong> fatty acids. An en<strong>on</strong>e-c<strong>on</strong>taining triglyceride w<strong>as</strong> obtained by an<br />
envir<strong>on</strong>mentally friendly chemical procedure from high oleic sunflower oil that could be an<br />
interesting alternative to epoxidized vegetable oils to produce thermosets by crosslinking<br />
with c<strong>on</strong>venti<strong>on</strong>al aromatic diamines. In a similar way, triglycerides c<strong>on</strong>taining sec<strong>on</strong>dary<br />
allylic alcohols can be obtained, that can be further functi<strong>on</strong>alised with acrylate or<br />
phosphorus-c<strong>on</strong>taining derivatives to obtain flame retardant themosets. We also obtained<br />
organic-inorganic hybrid materials with promising properties <strong>for</strong> optical applicati<strong>on</strong>s by the<br />
hydrosilylati<strong>on</strong> of alkenyl-terminated fatty acid derivatives <strong>and</strong> biob<strong>as</strong>ed polyhedral<br />
oligomeric silsesquioxanes-nanocomposites. Moreover, we described the preparati<strong>on</strong> of a<br />
new family of epoxidized methyl oleate-b<strong>as</strong>ed polyether polyols which were used in the<br />
synthesis of polyurethanes with specific applicati<strong>on</strong>s: silic<strong>on</strong>-c<strong>on</strong>taining polyurethanes with<br />
enhanced flame-retardant properties <strong>and</strong> polyurethane networks with potential applicati<strong>on</strong>s<br />
in biomedicine.<br />

tom<strong>as</strong>.vlcek@synpo.cz<br />
In this work we have studied possibility to apply chemo-enzymatic catalysis <strong>for</strong> preparati<strong>on</strong><br />
of new types of oil polyols. Starting raw materials were methylesters of<br />
hydroxyfuncti<strong>on</strong>alized fatty acids derived from c<strong>as</strong>tor oil, hydro<strong>for</strong>mylated soybean oil, <strong>and</strong><br />
epoxidized soybean oil ring opened with low molecular weight (poly)alcohols. Reacting<br />
these fatty acids with green growing centers such <strong>as</strong> 1.3-propanediol or glycerol we were<br />
able to synthesize 100 % renewable c<strong>on</strong>tent polyols differing in molecular weight, <strong>and</strong><br />
hydroxyl group’s functi<strong>on</strong>ality. We catalyzed the c<strong>on</strong>densati<strong>on</strong> reacti<strong>on</strong>s with up to 5 wt. %<br />
of immobilized C<strong>and</strong>ida antarctica lip<strong>as</strong>e B (Novozym 435). Setting up the reacti<strong>on</strong><br />
temperature to 70 °C <strong>and</strong> applying low pressure we allowed e<strong>as</strong>y removal of a side<br />
product, methanol. Curing the synthesized oil polyols with aliphatic <strong>and</strong> aromatic type of<br />
isocyanate we prepared model polyurethane c<strong>as</strong>t resins <strong>and</strong> evaluated physicalmechanical<br />
properties of these materials. We will discuss results of our work in our<br />

New sizing agents from natural origin were obtained by reacti<strong>on</strong> between maleic anhydride<br />
<strong>and</strong> esters from vegetable oils <strong>and</strong> mainly alkyl oleates. They bel<strong>on</strong>g to the alkenyl<br />
succinic anhydrides family (ASA).<br />
Paper hydrophobati<strong>on</strong>, which limits water penetrati<strong>on</strong>, relies up<strong>on</strong> the reacti<strong>on</strong> between<br />
the hydroxyl f<strong>on</strong>cti<strong>on</strong>s of cellulose <strong>and</strong> the anhydride moiety of ASA.<br />
Our vegetable ASA (oleo-ASA) are characterized by a maximum compositi<strong>on</strong> in C18:1 <strong>and</strong><br />
a varying terminal ester moiety. More than thirty oleo-ASA were tested <strong>as</strong> paper sizing<br />
agents at laboratory scale. Am<strong>on</strong>g them, three oleo-ASA presented a sizing <strong>and</strong> an<br />
emulsi<strong>on</strong> behaviour equivalent to the <strong>on</strong>e obtained with petrochemical ASA, comm<strong>on</strong>ly<br />
used in industry. Moreover, their hydrolysis in diacid is two-fold slower <strong>and</strong> their resistance<br />
to stripping phenomen<strong>on</strong> is ten-fold higher. Their use would then allow l<strong>on</strong>ger emulsi<strong>on</strong><br />
storage <strong>and</strong> fewer deposits in air ducts.<br />
These advantages make them excellent c<strong>and</strong>idates to the substituti<strong>on</strong> of ASA from fossil<br />
origin. Once the synthesis <strong>and</strong> purificati<strong>on</strong> of the three preceding molecules optimized, <strong>on</strong>e<br />
am<strong>on</strong>g them h<strong>as</strong> been successfully tested <strong>as</strong> sizing agent at a 100 kg paper machine pilot<br />
scale.<br />

Use of vegetable oil b<strong>as</strong>ed thermosetting resins in compound st<strong>on</strong>e<br />
Technology<br />

Unsaturated orthopthalic polyester resins (hereafter indicated <strong>as</strong> UP resins), dissolved in<br />
styrene, are widely used <strong>as</strong> binders to aggregate st<strong>on</strong>e <strong>and</strong> other inorganic raw materials<br />
in the producti<strong>on</strong> of compound st<strong>on</strong>e slabs using vibratory compacti<strong>on</strong> in a vacuum<br />
envir<strong>on</strong>ment, patented worldwide <strong>as</strong> Bret<strong>on</strong>st<strong>on</strong>e Technology.<br />
The use of UP resins involves some technical inc<strong>on</strong>veniences: both resin <strong>and</strong> styrene<br />
m<strong>on</strong>omer are oil-b<strong>as</strong>ed, hence they come from n<strong>on</strong>-renewable sources <strong>and</strong> their cost<br />
mainly depends <strong>on</strong> the value of crude oil; due to its high volatility rate, styrene is a<br />
dangerous chemical, which involves the designing of complex <strong>and</strong> expensive intake <strong>and</strong><br />
burning plants.<br />
Many ef<strong>for</strong>ts are dedicated to the development of a new organic binder, having similar<br />
properties to those of UP resins, which may solve these difficulties.<br />
We have found that chemically modified vegetable oil could be used <strong>as</strong> new renewable<br />
raw material: the epoxidati<strong>on</strong> of vegetable oils with a high iodine number (such <strong>as</strong> soybean<br />
<strong>and</strong> linseed oil) <strong>for</strong>ms epoxidated oils which are cured with aliphatic dicarboxilic anhydride,<br />
preferably in liquid state. The curing process must be accelerated using a b<strong>as</strong>ic catalyst.<br />
The new resin c<strong>on</strong>tains more than 50% by weight of renewable raw materials <strong>and</strong> c<strong>on</strong>tains<br />
no volatile organic comp<strong>on</strong>ents.<br />
The properties of both new thermosetting resin <strong>and</strong> compound st<strong>on</strong>es produced in this<br />
way are even better than traditi<strong>on</strong>al <strong>on</strong>es. In fact, the mechanical properties (such <strong>as</strong> the<br />
flexural strength <strong>and</strong> the water absorpti<strong>on</strong>) <strong>and</strong> the aesthetic effect (valuated technically by<br />
the gloss value) of the industrial slab remain c<strong>on</strong>stant, but the resistance to weather<br />
c<strong>on</strong>diti<strong>on</strong>s (evaluated by QUV panel) is incre<strong>as</strong>ed. The latter feature permits the use of<br />
compound st<strong>on</strong>e in many outdoor applicati<strong>on</strong>s.

Life cycle <strong>as</strong>sessment of high per<strong>for</strong>mance polyamides<br />

Introducti<strong>on</strong><br />
Although fossil carb<strong>on</strong> sources make up less than 10% of all materials utilised, there is<br />
currently intensive discussi<strong>on</strong> in the chemical industry <strong>on</strong> the use of renewable raw<br />
materials to produce fine chemicals <strong>and</strong> also m<strong>on</strong>omers <strong>for</strong> polymer producti<strong>on</strong>.<br />
In Brazil, <strong>for</strong> instance, Br<strong>as</strong>kem <strong>and</strong> DOW are planning to produce ethylene <strong>and</strong> then<br />
polyethylene from sugarcane-b<strong>as</strong>ed ethanol. This is just <strong>on</strong>e example of recent attempts to<br />
produce known b<strong>as</strong>ic petrochemical materials from renewable raw materials.<br />
The approach is somewhat c<strong>on</strong>troversial, however, because the starting compound,<br />
sucrose, h<strong>as</strong> a carb<strong>on</strong> to oxygen ratio of 1:1, while the target polyethylene molecule is a<br />
pure hydrocarb<strong>on</strong>. Even <strong>as</strong>suming maximum theoretical yields, more than three metric<br />
t<strong>on</strong>s of sugar are required to produce <strong>on</strong>e metric t<strong>on</strong> of polyethylene.<br />
On the other h<strong>and</strong>, synthetic routes b<strong>as</strong>ed <strong>on</strong> renewable raw materials to produce b<strong>as</strong>ic<br />
chemicals had been used industrially <strong>for</strong> many years, until such plants became<br />
unec<strong>on</strong>omical with the advent of highly cost-effective cracked products from fossil carb<strong>on</strong><br />
sources. The research ef<strong>for</strong>t required <strong>for</strong> a return to the earlier approach would there<strong>for</strong>e<br />
be fairly small. The slight technological risk exists, however, that it might not be possible to<br />
build up the relevant patent portfolio.<br />
In another approach, “new” m<strong>on</strong>omers are produced from renewable raw materials. An<br />
example is provided by DuP<strong>on</strong>t's biotechnologically produced 1,3-propanediol. In<br />
polyesters such <strong>as</strong> Sor<strong>on</strong>a <strong>and</strong> Hytrel, this diol produces materials with new properties.<br />
Patent protecti<strong>on</strong> <strong>for</strong> substances <strong>and</strong> applicati<strong>on</strong>s is undoubtedly possible here. However,<br />
new materials must be entered in the relevant registers of chemicals <strong>and</strong> launched <strong>on</strong> the<br />
market.<br />
Applicati<strong>on</strong>-oriented characterisati<strong>on</strong> <strong>and</strong> market launch of new materials cannot be<br />
delayed until the new biotechnological producti<strong>on</strong> methods <strong>for</strong> the relevant m<strong>on</strong>omers<br />
become available. A producti<strong>on</strong> plant <strong>for</strong> these m<strong>on</strong>omers must there<strong>for</strong>e be built, at le<strong>as</strong>t<br />
<strong>on</strong> a pilot scale, which allows their synthesis by "cl<strong>as</strong>sical" chemical methods.<br />

Polyamides from <strong>Renewable</strong> Raw Materials<br />
Polyamides are a cl<strong>as</strong>s of materials of which representatives b<strong>as</strong>ed <strong>on</strong> renewable raw<br />
materials have been known <strong>for</strong> at le<strong>as</strong>t 50 years. Most of these are b<strong>as</strong>ed <strong>on</strong> c<strong>as</strong>tor oil <strong>and</strong><br />
its cracked product ricinoleic acid methyl ester.<br />
Boiling with NaOH produces sebacic acid. According to Arnold <strong>and</strong> Smolinsky 1) , pyrolytic<br />
cracking at temperatures above 500°C produces 10-undecylenic acid, which is c<strong>on</strong>verted<br />
in further reacti<strong>on</strong> steps to 11-amino carboxylic acid <strong>and</strong> PA11. Other representatives of<br />
the cl<strong>as</strong>s of polyamides b<strong>as</strong>ed <strong>on</strong> renewable raw materials are PA610 <strong>and</strong> PA1010, both<br />
of which are b<strong>as</strong>ed <strong>on</strong> sebacic acid.<br />
In the above processes, significant amounts of by-products <strong>and</strong> w<strong>as</strong>te are unavoidably<br />
produced.<br />
This is why, in the 1970s, polyamides were developed from petrochemical raw materials,<br />
which process generates significantly less w<strong>as</strong>te. PA12 is a typical example of such<br />
compounds.<br />
Polyamides from <strong>Renewable</strong> Raw Materials—Back to the Future?<br />
Following the rapid growth of petrochemical-b<strong>as</strong>ed polyamides during the final decades of<br />
the l<strong>as</strong>t century, there h<strong>as</strong> been incre<strong>as</strong>ed interest over the l<strong>as</strong>t few years in sustainable<br />
products, resulting in intensified marketing of fatty-acid b<strong>as</strong>ed polyamides <strong>as</strong><br />
biopolyamides.<br />
At the K’2007, BASF announced the re-introducti<strong>on</strong> of PA610 <strong>and</strong> DuP<strong>on</strong>t of PA1010. For<br />
the l<strong>as</strong>t couple of years, Arkema h<strong>as</strong> been advertising its own PA11 <strong>as</strong> a biopolyamide.<br />
It must be pointed out, however, that the underlying synthetic methods will c<strong>on</strong>tinue to be<br />
b<strong>as</strong>ed <strong>on</strong> the above menti<strong>on</strong>ed chemistry, with high proporti<strong>on</strong>s of by-products <strong>and</strong> w<strong>as</strong>te.<br />
Polyamides from renewable raw materials there<strong>for</strong>e c<strong>on</strong>tinue to offer promise <strong>for</strong> the<br />
future: The t<strong>as</strong>k that lies ahead is to combine the sustainability of renewable raw materials<br />
with the sustainability <strong>and</strong> selectivity of petrochemical producti<strong>on</strong> methods.<br />
In this talk we will discuss <strong>and</strong> compare the various producti<strong>on</strong> methods <strong>for</strong> polyamides.<br />
Property profiles of polyamides from renewable raw materials <strong>and</strong> of their petrochemical<br />
analogues will be discussed. First results from a life cycle <strong>as</strong>sessment of different<br />
polyamides will be discussed <strong>as</strong> well. Finally, suggesti<strong>on</strong>s will be proposed <strong>as</strong> to how the<br />
sustainability of the resources can be combined with “green” chemistry.<br />

Introducti<strong>on</strong><br />
The cleavage of oleic acid via oz<strong>on</strong>olysis is the industrially applied process <strong>for</strong> the<br />
synthesis of azelaic acid from renewables. Alternatives are in dem<strong>and</strong> due to safety<br />
c<strong>on</strong>cerns of oz<strong>on</strong>e h<strong>and</strong>ling. Recently the authors reported <strong>on</strong> the epoxidati<strong>on</strong> of methyl<br />
oleate with molecular oxygen in the presence of aldehydes. 1 Now the cleavage of oleic<br />
acid or methyl oleate using this system <strong>and</strong> additi<strong>on</strong>ally OsO4 or pot<strong>as</strong>sium osmate <strong>as</strong><br />
catalysts is presented.<br />
Experimental<br />
In a typical experiment, 2 mmol substrate, 7.5 mmol aldehyde, 0.04 mmol OsO4 or<br />
K2OsO4�2H2O <strong>and</strong> 50 mg azobisisobutyr<strong>on</strong>itrile were placed in a 100 ml Buechi gl<strong>as</strong>s<br />
autoclave <strong>and</strong> were dissolved in 20 ml of the appropriate solvent. Then the autoclave w<strong>as</strong><br />
pressurized with 4 bar O2 <strong>and</strong> stirred at 70-90°C <strong>for</strong> 1-4 hours. The progress of the<br />
reacti<strong>on</strong> w<strong>as</strong> c<strong>on</strong>trolled by GC-MS.<br />
Results<br />
M<strong>on</strong>omethyl azelate 4 (R=CH3) <strong>and</strong> pelarg<strong>on</strong>ic acid 5 were the main products in the Oscatalyzed<br />
oxidati<strong>on</strong> of methyl oleate 1 (R=CH3) with O2/aldehyde besides varying amounts<br />
of the epoxide 2 <strong>and</strong> the diol 3, where<strong>as</strong> azelaic acid (4, R=H) w<strong>as</strong> solely obtained from<br />
oleic acid (1, R=H). However, a comparative applicati<strong>on</strong> of RuO4 or RuO2 instead of Oscatalysts<br />
did not lead to cleavage products.<br />
The simultaneous <strong>for</strong>mati<strong>on</strong> of the cleavage products 4 <strong>and</strong> 5 <strong>as</strong> well <strong>as</strong> of the epoxide 2<br />
<strong>and</strong> the diol 3 is interpreted mechanistically <strong>as</strong> parallel reacti<strong>on</strong>s (route A-C), this<br />
<strong>as</strong>sumpti<strong>on</strong> w<strong>as</strong> supported by m<strong>on</strong>itoring the course of reacti<strong>on</strong>. Epoxide 2 seems to be<br />
evolved according both to a radicalic <strong>and</strong> n<strong>on</strong>-radicalic pathway. The <strong>for</strong>mati<strong>on</strong> of 2 in 42%<br />
yield by oxidati<strong>on</strong> of methyl oleate in the presence of 2,6-di-tert.-butyl-4-methyl-phenol<br />
argues <strong>for</strong> a n<strong>on</strong>-radicalic mechanism, probably peracid is generated from the aldehyde<br />
via Os-catalysis. A further c<strong>on</strong>versi<strong>on</strong> of 2 under these c<strong>on</strong>diti<strong>on</strong>s did not lead to 3 but <strong>on</strong>ly<br />
to a minor degree to 9- or 10-keto derivatives.<br />

The diol 3 originated supposably by direct Os-catalyzed dihydroxylati<strong>on</strong> of 1 using in situ<strong>for</strong>med<br />
peracid. This guess w<strong>as</strong> drawn <strong>on</strong> the incre<strong>as</strong>e in yield of 3, if the reacti<strong>on</strong><br />
c<strong>on</strong>diti<strong>on</strong>s were adapted to known optimal dihydroxylati<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s (e.g. additi<strong>on</strong> of<br />
diazabicyclooctane, solvent DMF or MeCN/H2O/ethyl acetate). A possible acid-catalyzed<br />
cleavage of 2 to 3 or of 3 to 4 <strong>and</strong> 5 w<strong>as</strong> found to a minor degree. The direct cleavage of<br />
the double b<strong>on</strong>d of 1 to 4 <strong>and</strong> 5, most likely via a glycolate complex, w<strong>as</strong> also presumed to<br />
be n<strong>on</strong>-radicalic due to significant amounts of products, even under applicati<strong>on</strong> of a radical<br />
scavenger. Also in that c<strong>as</strong>e, the reacti<strong>on</strong> of O2 with the aldehyde to peracid is likely. On<br />
the b<strong>as</strong>is of the experimental results, the reacti<strong>on</strong> pathways B <strong>and</strong> C to 4 <strong>and</strong> 5, discussed<br />
in Figure 1, seem not to be the preferred routes at le<strong>as</strong>t. In summary, the obtained yields<br />
of 5 (R=CH3) amounted to 50-70%. Suitable solvents were acet<strong>on</strong>e or dichloromethane,<br />
more polar or aqueous-organic mixtures decre<strong>as</strong>ed the yield.<br />
If oleic acid w<strong>as</strong> used <strong>as</strong> substrate under equal reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s, surprisingly <strong>on</strong>ly the<br />
<strong>for</strong>mati<strong>on</strong> of 4 <strong>and</strong> 5 in about 50 % yield (n<strong>on</strong>-optimized) w<strong>as</strong> observed.<br />

Biodiesel comprises fatty acid methyl esters with various chain lengths. It h<strong>as</strong> clear<br />
envir<strong>on</strong>mental advantages compared to fossil fuels, nevertheless, some drawbacks rise<br />
from its limited shelf life, corrosi<strong>on</strong> in vehicle engines, <strong>and</strong> lower energy value. These are<br />
mainly related to oxygen c<strong>on</strong>tent of biodiesel, which should be removed. Possible ways <strong>for</strong><br />
upgrading are pyrolysis [1] or hydrogenati<strong>on</strong> [2,3]. In presence of H2 <strong>and</strong> noble metal<br />
catalysts (Pd, Ru, Ni) the latter route selectively <strong>for</strong>ms hydrocarb<strong>on</strong>s. Though H2 additi<strong>on</strong><br />
leads to high yields of desired paraffins, the use of external H2 sources lowers process<br />
ec<strong>on</strong>omy. A hydrogen-free route may benefit from decompositi<strong>on</strong> of by-product glycerol<br />
that generates H2 in situ. This work focused <strong>on</strong> model studies to investigate the hydrogenfree<br />
deoxygenati<strong>on</strong> of C8, C12, <strong>and</strong> C18 acids exclusively.<br />
Supported Ni <strong>and</strong> Pd catalysts (1-10 wt-%) were prepared by impregnati<strong>on</strong> of ZrO2, active<br />
carb<strong>on</strong>, zeolites, <strong>and</strong> hydrotalcites. Autoclaves (25 ml) served <strong>for</strong> catalytic tests. Catalysts<br />
were reduced in situ with H2 (300 °C, 2 h) <strong>and</strong> the vessel w<strong>as</strong> flushed with N2. Then,<br />
soluti<strong>on</strong>s of carboxylic acids in dodecane or tetralin were added <strong>and</strong> the reacti<strong>on</strong> w<strong>as</strong><br />
started.<br />
Initial catalyst survey w<strong>as</strong> d<strong>on</strong>e with lauric acid (C12) at 300 °C. With supported Ni<br />
catalysts, highest c<strong>on</strong>versi<strong>on</strong> w<strong>as</strong> found <strong>on</strong> 10%Ni/ZrO2 (59 %) <strong>and</strong> 5%Ni/ZrO2 (57 %), but<br />
alkane selectivity w<strong>as</strong> little. In a sec<strong>on</strong>d series, Pd catalysts supported <strong>on</strong> active carb<strong>on</strong><br />
were tested. The best per<strong>for</strong>ming catalyst w<strong>as</strong> 10%Pd/C with 37 % undecane yield at 68<br />
% c<strong>on</strong>versi<strong>on</strong> of lauric acid. Such Pd catalysts then were used <strong>for</strong> deoxygenati<strong>on</strong> of<br />
caprylic acid (C8) <strong>and</strong> stearic acid (C18). At similar reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s (300 °C, 6 h), chain<br />
length of carboxylic acid h<strong>as</strong> a str<strong>on</strong>g impact <strong>on</strong> c<strong>on</strong>versi<strong>on</strong> <strong>as</strong> well <strong>as</strong> alkane selectivity<br />
(caprylic acid: X = 35 %, S = 54 %; lauric acid: X = 55 %, S = 68 %, stearic acid: X = 93 %,<br />
S = 13 %). The observed maximum in selectivity may be due to incre<strong>as</strong>ed cracking <strong>as</strong> a<br />
side reacti<strong>on</strong>, the probability of which incre<strong>as</strong>es with number of carb<strong>on</strong> atoms <strong>and</strong> b<strong>on</strong>ds.<br />
At 300 °C, c<strong>on</strong>versi<strong>on</strong> without H2 additi<strong>on</strong> may not be favorable <strong>for</strong> l<strong>on</strong>g chain carboxylic<br />
acids anymore.<br />
Further work aimed at optimizati<strong>on</strong> of reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s with 10%Pd/C catalyst. Raising<br />
temperature also w<strong>as</strong> found to have a str<strong>on</strong>g promoti<strong>on</strong>al effect <strong>on</strong> carboxylic acid<br />
c<strong>on</strong>versi<strong>on</strong> <strong>as</strong> well <strong>as</strong> alkane selectivity. Incre<strong>as</strong>ing pressure lowered c<strong>on</strong>versi<strong>on</strong>, but<br />
improved selectivity towards alkane. Characterizati<strong>on</strong> of spent catalyst 10%Pd/C showed a<br />
slight loss in Pd c<strong>on</strong>tent due to leaching, but no agglomerati<strong>on</strong> of metal particles.<br />

Flame retardant polyesters from renewable resources via ADMET<br />

Polyesters are widely used <strong>for</strong> textile fibers, technical fibers, films, bottles or <strong>as</strong> a finish <strong>on</strong><br />
high-quality wood products. The dem<strong>and</strong> of polyesters in 2006 is an estimated 35 milli<strong>on</strong><br />
t<strong>on</strong>s <strong>and</strong> will grow annually by 9%.[1] Due to envir<strong>on</strong>mental c<strong>on</strong>cerns much work is<br />
devoted to the industrial use of products from renewable resources, <strong>and</strong> <strong>for</strong> this re<strong>as</strong><strong>on</strong> the<br />
development of polymeric materials, such <strong>as</strong> polyesters, from renewable resources h<strong>as</strong><br />
attracted much attenti<strong>on</strong>.[2] On the other h<strong>and</strong>, many kinds of flame retardants (FRs) have<br />
been tested to improve the flame retardancy of polyesters <strong>and</strong> have been applied to<br />
commercial products. Am<strong>on</strong>g these, phosphorous FR <strong>and</strong> halogenated FR are the most<br />
comm<strong>on</strong>. However, many kinds of halogenated FR, especially brominated FR, are<br />
restricted in many countries due to the <strong>for</strong>mati<strong>on</strong> of dioxin under combusti<strong>on</strong>. There<strong>for</strong>e<br />
most of the inherent FR polyesters are now produced using phosphorous FR by blending<br />
<strong>and</strong>/or copolymerizing with flame retardants. However, to obtain efficient flame retardancy<br />
by blending, high amounts of the flame retardant agent must be added <strong>and</strong> usually the<br />
polymer properties are affected. Also, when a blended fiber is w<strong>as</strong>hed, the blended flame<br />
retardants migrate to the fiber surface, leading to decre<strong>as</strong>ed flame retardancy <strong>and</strong><br />
incre<strong>as</strong>ed danger <strong>for</strong> the customers. Because of these problems, the copolymerizing<br />
method is becoming more comm<strong>on</strong>.<br />
Acyclic diene metathesis polymerizati<strong>on</strong> (ADMET) h<strong>as</strong> been shown to be an efficient tool<br />
<strong>for</strong> the synthesis of a wide variety of polymers <strong>and</strong> polymer architectures that are not<br />
available using other polymerizati<strong>on</strong> methods.[3] Am<strong>on</strong>g them, polyesters can be prepared<br />
with molecular weights that range between 20.000 <strong>and</strong> 70.000. In the present work, a<br />
renewable phosphorus c<strong>on</strong>taining m<strong>on</strong>omer bearing two 10-undecenoic acid moieties h<strong>as</strong><br />
been homopolymerized <strong>and</strong> copolymerized with a 10-undecenoic acid derived m<strong>on</strong>omer[4]<br />
via ADMET using the Grubbs sec<strong>on</strong>d generati<strong>on</strong> metathesis catalyst. Polymers with Mn up<br />
to 65.000 were obtained in absence of solvent. This procedure allowed us to synthesize a<br />
variety of polyesters with c<strong>on</strong>trolled phosphorus c<strong>on</strong>tents which are promising c<strong>and</strong>idates<br />
<strong>for</strong> flame retardant materials.<br />

Plant oils c<strong>on</strong>stitute a cl<strong>as</strong>s of renewable raw materials which can produce a large variety<br />
of chemicals useful <strong>for</strong> industry. The cross-metathesis of unsaturated fatty esters, derived<br />
from seed oils, with functi<strong>on</strong>alized olefins h<strong>as</strong> potential to generate bifuncti<strong>on</strong>al<br />
compounds, <strong>as</strong> it h<strong>as</strong> been shown by reacti<strong>on</strong>s with acrylates[1]. The objective of our<br />
presentati<strong>on</strong> will be to describe, with some practical <strong>as</strong>pects, the cross-metathesis<br />
reacti<strong>on</strong>s of both terminal <strong>and</strong> internal double b<strong>on</strong>d c<strong>on</strong>taining esters, arising from seed<br />
oils, with acryl<strong>on</strong>itrile. This metathesis w<strong>as</strong> per<strong>for</strong>med using ruthenium catalysts <strong>and</strong> led to<br />
bifuncti<strong>on</strong>al nitrile-esters with high c<strong>on</strong>versi<strong>on</strong>s [2]. TON improvement w<strong>as</strong> achieved by<br />
slow additi<strong>on</strong> of catalyst.<br />
It will be shown that the metathesis catalyst residue can be used <strong>as</strong> a hydrogenati<strong>on</strong><br />
catalyst in a sequential cross-metathesis/hydrogenati<strong>on</strong> process leading to saturated<br />
nitrile-esters.<br />
The prepared bifuncti<strong>on</strong>al nitrile-esters are precursors of amino acid m<strong>on</strong>omers <strong>for</strong> the<br />
producti<strong>on</strong> of polyamides from renewable resources.<br />

bifuncti<strong>on</strong>al compounds, products of the c<strong>on</strong>versi<strong>on</strong> of fatty acids, can serve <strong>as</strong> “soft”,<br />
amorphous m<strong>on</strong>omer. The synthesis of bifuncti<strong>on</strong>al m<strong>on</strong>omers from oleic acid <strong>and</strong> their<br />
derivatives <strong>for</strong> the producti<strong>on</strong> of polymers b<strong>as</strong>ed <strong>on</strong> renewable resources is thus useful in<br />
the field of thermopl<strong>as</strong>tic el<strong>as</strong>tomers.<br />
Organo-metal-catalyzed metathesis [1] of C18-compounds, b<strong>as</strong>ed <strong>on</strong> oleic acid [2], oleic<br />
acid esters [3, 4] <strong>and</strong> other readily available educts from the tenside industry such <strong>as</strong> oleyl<br />
alcohol [5], oleic amide <strong>and</strong> amines <strong>as</strong> feedstock can supply the necessary bifuncti<strong>on</strong>al<br />
m<strong>on</strong>omers <strong>for</strong> polyc<strong>on</strong>densati<strong>on</strong>. The metathesis of oleic acid provides two olefins,<br />
octadec-9-ene <strong>and</strong> octadec-9-ene-1,18-dicarboxylic acid, both C18 compounds. The<br />
homometathesis of oleic acid <strong>and</strong> derivatives -functi<strong>on</strong>alized fatty�,�there<strong>for</strong>e is an<br />
interesting way to synthesize acid compounds.<br />
To be applied later in industry, the producti<strong>on</strong> of these m<strong>on</strong>omers must be scaled up now.<br />
Ruthenium compounds <strong>for</strong> metathesis bel<strong>on</strong>g to a cl<strong>as</strong>s of extremely efficient catalysts,<br />
tolerant to many functi<strong>on</strong>al groups. Technical grade educts may provide catalyst pois<strong>on</strong>ing<br />
effects. Especially nitrogen-c<strong>on</strong>taining compounds present many problems due to their<br />
b<strong>as</strong>icity. We report the metathetic synthesis of bifuncti<strong>on</strong>al products, b<strong>as</strong>ed <strong>on</strong> nitrogen<br />
b<strong>as</strong>ed derivatives. Ruthenium-b<strong>as</strong>ed homometathesis of oleic acid esters, oleyl alcohol,<br />
oleic acid amides <strong>and</strong> oleyl amines have been c<strong>on</strong>ducted. For esters <strong>and</strong> oleyl alcohol,<br />
maximum c<strong>on</strong>versi<strong>on</strong> could be achieved, even with technical grade educts without further<br />
pretreatment. Even solvent-free synthesis at low catalyst loadings w<strong>as</strong> possible. The C18diester<br />
w<strong>as</strong> obtained via thin film evaporati<strong>on</strong>, the diol w<strong>as</strong> obtained via precipitati<strong>on</strong> <strong>and</strong><br />
recrystallizati<strong>on</strong>.<br />
Oleyl amine itself could not be c<strong>on</strong>verted, but protected amines, like oleyl amides or oleyl<br />
n-alkyl-amines can be c<strong>on</strong>verted. The metathetical c<strong>on</strong>versi<strong>on</strong> of amides provide a lower<br />
yield in bifuncti<strong>on</strong>al compounds compared to diester <strong>and</strong> diol, but is nevertheless<br />
interesting, because the diamide precipitates during reacti<strong>on</strong> <strong>and</strong> is e<strong>as</strong>ily isolized via<br />
centrifugati<strong>on</strong> <strong>and</strong> recrystallizati<strong>on</strong>.<br />

The use of renewable feedstock like Glycerol <strong>for</strong> producing important industrial chemicals<br />
having bulk dem<strong>and</strong> is the priority of 21st century. Glycerol is an important by product of<br />
biodiesel manufacturing which is produced by transesterficati<strong>on</strong> during the producti<strong>on</strong> of<br />
biodiesel fuel. Approximatly 10 kg of glycerol is produced <strong>for</strong> every 100 kg of oil taken <strong>for</strong><br />
producti<strong>on</strong> of biodiesel. With the total producti<strong>on</strong> of biodiesel in thous<strong>and</strong>s of t<strong>on</strong>s, huge<br />
amount of glycerol is also produced <strong>as</strong> a by product. 1 It h<strong>as</strong> been estimated that by 2010<br />
the overall producti<strong>on</strong> of glycerol will touch 1.2 milli<strong>on</strong> t<strong>on</strong>s. The cost of B100 type<br />
biodiesel can be reduced from US$ 0.63 to US$ 0.35 provided the use of glycerol is<br />
enhanced <strong>for</strong> the producti<strong>on</strong> of value added products.2 In spite of green origin <strong>and</strong> over<br />
producti<strong>on</strong> the scientific community had not been able to fully explore potential usefulness<br />
of this naturally occurring molecule <strong>for</strong> making value added products.<br />
Recently our research group reported synthesis of β-Bromo Glycerol M<strong>on</strong>oethers directly<br />
from α-Olefins by cohalogenati<strong>on</strong> protocol.3 With the c<strong>on</strong>tinuati<strong>on</strong> of our work we have<br />
developed glycerol b<strong>as</strong>ed pyridinium surfactants <strong>and</strong> compared its properties with some<br />
commercially available surfactants. We found better surface <strong>and</strong> biological properties such<br />
<strong>as</strong> low cytotoxicity towards animal cell line <strong>and</strong> better DNA binding capability of new<br />
glycerol b<strong>as</strong>ed cati<strong>on</strong>ic surfactants. As the producti<strong>on</strong> of cati<strong>on</strong>ic surfactants amounts to<br />
350000-500000 t<strong>on</strong>es per annum.4 The replacement of commercially available cati<strong>on</strong>ic<br />
surfactants with new glycerol b<strong>as</strong>ed surfactants will check loss of energy <strong>and</strong> resources<br />
due to over producti<strong>on</strong> of glycerol.<br />

Polymerizati<strong>on</strong> of triglycerides is usually carried out by attaching a polymerizable group to<br />
the triglyceride [1]. Polymers derived from such m<strong>on</strong>omers have low c<strong>on</strong>nectivity <strong>and</strong> low<br />
mechanical properties due to the bulky structure of the m<strong>on</strong>omer. This manifests itself in<br />
low fracture toughness of the polymers obtained. In this work we changed our strategy by<br />
starting first with a suitably substituted polymer having a re<strong>as</strong><strong>on</strong>able molecular weight <strong>and</strong><br />
attaching the triglyceride derivative to it. This strategy is bound to provide molecular<br />
weights that are higher <strong>and</strong> provide the entanglement lengths needed <strong>for</strong> higher fracture<br />
toughness.<br />
In this study, styrene maleic anhydride copolymer (SMA2000, Styrene:Maleic Anhydride<br />
2:1) is grafted <strong>and</strong>/or crosslinked with epoxidized methyl oleate, epoxidized soybean oil,<br />
methyl ricinoleate, c<strong>as</strong>tor oil <strong>and</strong> soybean oil diglyceride. B<strong>as</strong>e catalyzed epoxy-anhydride<br />
<strong>and</strong> alcohol-anhydride reacti<strong>on</strong>s were carried out by using the anhydride <strong>on</strong> SMA, the<br />
epoxy or sec<strong>on</strong>dary alcohol groups <strong>on</strong> the triglyceride b<strong>as</strong>ed m<strong>on</strong>omers. The<br />
characterizati<strong>on</strong>s of the products were d<strong>on</strong>e by DMA, TGA <strong>and</strong> IR spectroscopy. SMAepoxidized<br />
soy oil <strong>and</strong> SMA-c<strong>as</strong>tor oil polymers are crosslinked rigid infusible polymers.<br />
SMA-epoxidized soy oil <strong>and</strong> SMA2000-c<strong>as</strong>tor oil showed Tg’s at 70 <strong>and</strong> 66 ºC<br />
respectively. Dynamic moduli of the two polymers were 11.73 <strong>and</strong> 3.34 Mpa respectively.<br />
SMA-epoxidized methyl oleate, SMA-methyl ricinoleate <strong>and</strong> SMA-soy oil diglyceride<br />
polymers were soluble <strong>and</strong> thermopl<strong>as</strong>tic polymers <strong>and</strong> were characterized by TGA, GPC,<br />
DSC, NMR <strong>and</strong> IR spectroscopy.<br />

Unsaturated polyesters were chain extended with epoxidized soybean oil. The molecular<br />
weight incre<strong>as</strong>e w<strong>as</strong> m<strong>on</strong>itored using Gel Permeati<strong>on</strong> Chromatography. The obtained<br />
polymer w<strong>as</strong> characterized by FTIR <strong>and</strong> 1H-NMR, styrene solubility <strong>and</strong> gel time. The<br />
chain extended polyester w<strong>as</strong> then diluted with styrene <strong>and</strong> cured with a radical initiator<br />
<strong>and</strong> compared to a commercial reference polyester. Thermal <strong>and</strong> mechanical properties of<br />
the cured polyester were characterized by DMA <strong>and</strong> TGA. The results show that<br />
unsaturated polyesters can be chain extended with epoxidized soybean oil which<br />
substantially shortens the c<strong>on</strong>densati<strong>on</strong> polymerizati<strong>on</strong> during manufacture, without<br />
compromising their thermal <strong>and</strong> mechanical properties.<br />

Isocyanates are valuable compounds that are used widely in many applicati<strong>on</strong> are<strong>as</strong> of<br />
polymer industry. The most important area of use of isocyanates is to synthesize<br />
polyurethanes <strong>and</strong> polyure<strong>as</strong>. Important isocyanates, used in the polyurethane<br />
manufacturing, are 2, 4-toluene diisocyanate (2,4TDI), 2, 6-toluene diisocyanate (2,6TDI),<br />
4, 4’-diphenyl methane diisocyanate (MDI), 1, 6 hexamethyl diisocyanate (HMDI), xylene<br />
diisocyanate (XDI), <strong>and</strong> isophor<strong>on</strong>e diisocyanate (IPDI), all of which are petroleum derived<br />
[1-3].<br />
Isocyanates can be synthesized in many ways. The Curtius, Hoffman <strong>and</strong> Lossen<br />
rearrangements, which may involve nitrene <strong>as</strong> an intermediate, are not succesful <strong>for</strong> large<br />
scale operati<strong>on</strong>s [4].<br />
Literature search reveals a number of bio-b<strong>as</strong>ed polyurethanes. In almost all of them,<br />
c<strong>as</strong>tor oil w<strong>as</strong> used <strong>as</strong> a polyol source <strong>and</strong> petroleum b<strong>as</strong>ed isocyanates were used <strong>as</strong> the<br />
isocyanate [5-12]. There are no examples where the isocyanate is bio-b<strong>as</strong>ed. With the<br />
simple synthesis described in this work it is possible to obtain polyurethanes where both<br />
the isocyanate <strong>and</strong> polyol are bio-b<strong>as</strong>ed.<br />
In the first strategy, soybean oil isocyanates were obtained by substituti<strong>on</strong> reacti<strong>on</strong><br />
between allylically brominated soybean oil <strong>and</strong> AgNCO [13]. In the sec<strong>on</strong>d strategy,<br />
soybean oil w<strong>as</strong> reacted with iodine isocyanate reagent [14-15]. Additi<strong>on</strong> of iodo<br />
isocyanate to plant oils gives valuable intermediates. Similar to thiocyanogen additi<strong>on</strong>, just<br />
<strong>on</strong>e mole iodo isocyanate can be added to <strong>on</strong>e mol of polyunsaturated fatty acids. This<br />
means that <strong>on</strong>e mole unsaturated plant oil triglyceride can bind around three mol iodo<br />
isocyanate e<strong>as</strong>ily. Many positi<strong>on</strong>al isomers are obtained at the end of the both reacti<strong>on</strong>.<br />
The products are valuable intermediates to synthesize poly-urethanes <strong>and</strong> poly ure<strong>as</strong>.<br />
Synthesized soybean oil isocyanate <strong>and</strong> iodo isocyanate were polymerized with c<strong>as</strong>tor oil<br />
<strong>and</strong> glycerol. C<strong>as</strong>tor oil <strong>and</strong> glycerol polyurethane of soybean oil iodo isocyanate showed<br />
tensile strength of 140 KPa <strong>and</strong> 270 KPa respectively. On the other side, polyurethanes of<br />
soybean oil isocyanate with same triols showed tensile strength of 100 <strong>and</strong> 125 KPa<br />
respectively<br />

We investigated the synthesis of l<strong>on</strong>g-chained alkyl methyl ket<strong>on</strong>es systematically in order<br />
to optimize reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s, yields <strong>and</strong> purity of the products.<br />
We also report in this poster about new applicati<strong>on</strong>s of the microwave technology to<br />

Short Chain Sugar Amphiphiles: Alternative Oil Structuring Agents<br />
Swapnil R Jadhav, Praveen Kumar Vemula, <strong>and</strong> George John, City College of City<br />
University of New York, New York, USA; Jadhav sjadhav@gc.cuny.edu<br />
Owing to the need of developing envir<strong>on</strong>mentally benign functi<strong>on</strong>al materials by adopting<br />
green chemistry methods, usage of biorefinery c<strong>on</strong>cept <strong>for</strong> the development of biob<strong>as</strong>ed<br />
molecular building blocks of such materials h<strong>as</strong> emerged <strong>as</strong> a prime focus of the current<br />
research. The present study focus of developing sugar b<strong>as</strong>ed low molecular weight gels (a<br />
type of functi<strong>on</strong>al soft materials) by enzyme catalysis exemplifies the above approach. The<br />
underexplored open chain sugars (sugar alcohols) were chosen <strong>as</strong> hydrophilic moieties to<br />
develop low molecular weight gelators (LMWGs). Mannitol, sorbitol <strong>and</strong> xylitol were<br />
selected <strong>as</strong> representative sugar alcohols (headgroups) <strong>and</strong> series of amphiphiles were<br />
synthesized by attaching hydrophobic carboxylic acids at <strong>on</strong>e-end of the sugar using an<br />
enzyme-mediated regioselective transesterificati<strong>on</strong> reacti<strong>on</strong>. For c<strong>on</strong>trol tuning of<br />
hydrophobicity various carboxylic acids different chain length were attached (typically<br />
(CH2)4-14). The resulting amphiphiles were studied <strong>for</strong> their self-<strong>as</strong>sembling behavior in<br />
organic liquids. Only the amphiphiles with short chains {(CH2)4-8} were found to be<br />
efficient organogelators; immobilizing various solvents ranging from crude oil fracti<strong>on</strong>s to<br />
vegetable oils. In additi<strong>on</strong>, Effect of chiral <strong>and</strong> structural variati<strong>on</strong>s in sugar amphiphiles <strong>on</strong><br />
microstructure <strong>for</strong>mati<strong>on</strong> (resp<strong>on</strong>sible <strong>for</strong> immobilizati<strong>on</strong> of organic liquid) w<strong>as</strong> also<br />
investigated in detail. Furthermore, the efficiency of the short chain sugar amphiphiles <strong>as</strong> a<br />
healthy alternative structuring agents <strong>for</strong> vegetable oils compared to existing oil structuring<br />
agents w<strong>as</strong> studied <strong>and</strong> h<strong>as</strong> been dem<strong>on</strong>strated in this report.

Novel enzymes <strong>for</strong> lipid modificati<strong>on</strong><br />

Enzymes have received c<strong>on</strong>siderable <strong>and</strong> incre<strong>as</strong>ing attenti<strong>on</strong> in lipid modificati<strong>on</strong> over the<br />
l<strong>as</strong>t few years. In particular, hydrol<strong>as</strong>es have a high potential <strong>for</strong> applicati<strong>on</strong>s such <strong>as</strong> the<br />
lip<strong>as</strong>es-catalyzed interestificati<strong>on</strong> [1, 2] <strong>as</strong> an alternative <strong>for</strong> the hydrogenati<strong>on</strong> of fats or<br />
the preparati<strong>on</strong> of designer-fats [3].<br />
Many enzymes, however, do not fulfill all dem<strong>and</strong>s of a technical process. Properties such<br />
<strong>as</strong> stability under process c<strong>on</strong>diti<strong>on</strong>s or the chemical selectivity leave often much to<br />
improve. Together with this growing dem<strong>and</strong> <strong>for</strong> tailor-made lip<strong>as</strong>es goes the incre<strong>as</strong>ing<br />
knowledge about the molecular structures. C<strong>on</strong>siderable progress in molecular biology<br />
techniques h<strong>as</strong> made the cl<strong>on</strong>ing <strong>and</strong> expressi<strong>on</strong> of lip<strong>as</strong>es in bacteria <strong>and</strong> the subsequent<br />
improvement by techniques of state-of-the art protein design [4] possible.<br />
An alternative <strong>for</strong> the improvement of enzymes by protein design represents the screening<br />
<strong>for</strong> novel enzymes. The limited number of commercially available lip<strong>as</strong>es can be extended<br />
by high-throughput screening in enzyme collecti<strong>on</strong>s. Enzymes from metagenome<br />
represent a rich source <strong>for</strong> this purpose.<br />
Herein we present an outline <strong>and</strong> the scope of both techniques that can provide novel<br />
biocatalysts <strong>for</strong> new applicati<strong>on</strong>s in lipid-modificati<strong>on</strong>.<br />

Producti<strong>on</strong> of fine <strong>and</strong> bulk chemicals using silage <strong>as</strong> a renewable resource<br />
60<br />
Tim Sieker, <strong>and</strong> Rol<strong>and</strong> Ulber, University of Kaiserslautern, Kaiserslautern,<br />
Germany; tim.sieker@mv.uni-kl.de<br />
The presented work aims <strong>for</strong> the use of silage <strong>as</strong> a renewable resource <strong>for</strong> the<br />
fermentative producti<strong>on</strong> of bulk- <strong>and</strong> fine chemicals <strong>and</strong> is a cooperati<strong>on</strong> with the Institute<br />
of Thermal Process Engineering at the University of Kaiserslautern <strong>and</strong> the Institute of<br />
Biochemical Engineering at the Saarl<strong>and</strong> University.<br />
In 2006 321,300 ha of farml<strong>and</strong> were used <strong>for</strong> the producti<strong>on</strong> of gr<strong>as</strong>s <strong>and</strong> clover, yielding<br />
36,268,000 t of harvested gr<strong>as</strong>s clip. Thus, gr<strong>as</strong>s clip provides an enormous potential <strong>as</strong><br />
renewable resource in Germany. Since fresh gr<strong>as</strong>s clip is available <strong>on</strong>ly during summer<br />
<strong>and</strong> it decays if stored inappropriately, it is c<strong>on</strong>served by ensiling.<br />
In the ensiling process, the water-soluble carbohydrates are fermented to lactic acid,<br />
resulting in a pH-shift <strong>and</strong> thus the c<strong>on</strong>servati<strong>on</strong> of the silage. The processes in<br />
development are to use the remaining carbohydrates, including cellulose <strong>and</strong><br />
hemicellulose, <strong>as</strong> well <strong>as</strong> the lactic acid produced during ensiling. Aspired products are<br />
ethanol, 1,2-propanediole, itac<strong>on</strong>ic <strong>and</strong> succinic acid. Remnants <strong>and</strong> w<strong>as</strong>tes of the<br />
processes should be reuseable <strong>as</strong> animal food or in biog<strong>as</strong> producti<strong>on</strong>, resulting in a<br />
complete substantial <strong>and</strong> energetic utilisati<strong>on</strong> of the silage.<br />
In the presented work two strategies <strong>for</strong> the utilizati<strong>on</strong> of silage are pursued:<br />
First, a silage juice c<strong>on</strong>taining the water-soluble carbohydrates <strong>and</strong> the lactic acid is w<strong>on</strong><br />
directly from the silage by pressing. This silage juice can either be used directly <strong>as</strong> a<br />
cultivati<strong>on</strong> medium or by the isolati<strong>on</strong> of the c<strong>on</strong>tained lactic acid, the main product of<br />
ensiling, <strong>and</strong> its further use.<br />
Sec<strong>on</strong>dly, the hydrolysis of the celluloses <strong>and</strong> hemicelluloses c<strong>on</strong>tained in the silage is<br />
<strong>as</strong>pired. After the separati<strong>on</strong> of solid <strong>and</strong> liquid ph<strong>as</strong>es the latter, a mixture of organic<br />
acids produced during ensiling <strong>and</strong> pentoses <strong>and</strong> hexoses rele<strong>as</strong>ed during hydrolysis, is<br />
fermented.<br />
Taken together the described work is able to offer an all-se<strong>as</strong><strong>on</strong> renewable resource <strong>for</strong><br />
the producti<strong>on</strong> of b<strong>as</strong>e <strong>and</strong> fine chemicals <strong>and</strong> to incre<strong>as</strong>e the value of an agricultural<br />
product respectively to improve the ec<strong>on</strong>omics of biog<strong>as</strong> producti<strong>on</strong>.<br />

Enzymatic degradati<strong>on</strong> of pre-treated wood<br />
Seb<strong>as</strong>tian Poth, Magaly M<strong>on</strong>z<strong>on</strong>, Nils Tippkötter, <strong>and</strong> Rol<strong>and</strong> Ulber, University of<br />
Kaiserslautern, Germany; poth@mv.uni-kl.de<br />
The ec<strong>on</strong>omic dependency <strong>on</strong> fossil fuels <strong>and</strong> the changes of climate due to them h<strong>as</strong> led<br />
to an intensive search <strong>for</strong> renewable resources <strong>for</strong> the producti<strong>on</strong> of chemicals <strong>and</strong> fuels.<br />
At present there are several processes established which use sugar cane <strong>and</strong> corn <strong>for</strong> the<br />
producti<strong>on</strong> of bioethanol. As these crops are comm<strong>on</strong>ly used <strong>as</strong> food there is an ethical<br />
drive to use alternative resources <strong>for</strong> industrial processes. Promising feedstock <strong>for</strong> the<br />
chemical <strong>and</strong> fuel producti<strong>on</strong> are in this c<strong>on</strong>text the fermentable sugars derived from<br />
wooden celluloses <strong>and</strong> hemicelluloses by enzymatic hydrolysis. The great challenge in this<br />
regard is to design new simple <strong>and</strong> beneficial processes that can compete against<br />
c<strong>on</strong>venti<strong>on</strong>al petrochemical producti<strong>on</strong> processes.<br />
The most important step in these processes is the hydrolysis of the lignocellulosic material<br />
into the corresp<strong>on</strong>ding sugar m<strong>on</strong>omers, which can be fermented to ethanol <strong>for</strong> example.<br />
The aim of the presented work is to optimize the enzymatic hydrolysis with regard to the<br />
used substrates <strong>and</strong> the usage of hydrolysates <strong>for</strong> the fermentati<strong>on</strong> of alcohol. The<br />
substrates are cellulose <strong>and</strong> hemicellulose fracti<strong>on</strong>s obtained by thermo-chemical pretreatment<br />
of beech wood. This pre-treatment is carried out by our project partner at the<br />
Johann Heinrich v<strong>on</strong> Thünen Institute, Hamburg, Germany.<br />
Several commercially available enzymes, even thermo stable <strong>on</strong>es were tested <strong>on</strong> their<br />
ability to degrade these fracti<strong>on</strong>s. In first experiments it could be shown, that the enzymes<br />
can hydrolyse up to 40 % of the cellulosic fracti<strong>on</strong> into fermentable sugars within 24 h. The<br />
hemicellulosic fracti<strong>on</strong> already c<strong>on</strong>tains some m<strong>on</strong>omeric sugars which can be fermented.<br />
For this fracti<strong>on</strong> the use of hemicellul<strong>as</strong>es is investigated. All sugar c<strong>on</strong>taining<br />
hydrolysates <strong>and</strong> fracti<strong>on</strong>s were tested <strong>for</strong> their suitability <strong>as</strong> carb<strong>on</strong> source <strong>for</strong> a cofermentati<strong>on</strong><br />
of two different ye<strong>as</strong>ts to produce ethanol. The results showed that the<br />
additi<strong>on</strong> of a nitrogen source, vitamins <strong>and</strong> trace-elements is the <strong>on</strong>ly necessary<br />
preliminary step <strong>for</strong> the fermentati<strong>on</strong>. To incre<strong>as</strong>e the yield of sugars in the hydrolysates<br />
further optimizati<strong>on</strong>s were made, e.g. the incre<strong>as</strong>e of substrate c<strong>on</strong>centrati<strong>on</strong> <strong>and</strong> the<br />
amount of added enzymes w<strong>as</strong> investigated.<br />

PA X,20 from renewable resources via metathesis <strong>and</strong> catalytic amidati<strong>on</strong><br />

Polyamides (PA) are engineering pl<strong>as</strong>tics with various commercial applicati<strong>on</strong>s due to their<br />
outst<strong>and</strong>ing properties such <strong>as</strong> high durability, high hardness <strong>and</strong> rigidity [1]. Methods <strong>for</strong><br />
the producti<strong>on</strong> of polyamides by polyc<strong>on</strong>densati<strong>on</strong> of aliphatic diamines <strong>and</strong> dicarboxylic<br />
acids or the polyadditi<strong>on</strong> of lactams are often described in the literature. These articles are<br />
mostly dedicated to st<strong>and</strong>ard polyamides b<strong>as</strong>ed <strong>on</strong> depleting fossil resources. However,<br />
bio-b<strong>as</strong>ed polyamides are not yet well developed. The unique example of industrially<br />
produced 100% bio-b<strong>as</strong>ed polyamide is the AB-type polyamide-11 [2]. Synthesis of 100%<br />
bio-b<strong>as</strong>ed AABB type polyamides are not expected because of the n<strong>on</strong>-availability of biob<strong>as</strong>ed<br />
diamines. Meanwhile, research <strong>on</strong> routes to obtain diacids from glucose (adipic<br />
acid) or vegetable oils (azelaic acid, sebacic acid) <strong>for</strong> the producti<strong>on</strong> of partially biob<strong>as</strong>ed<br />
polyamides-6,6, -6,9, <strong>and</strong> -6,10 are under investigati<strong>on</strong> [3].<br />
Am<strong>on</strong>g various polyc<strong>on</strong>densati<strong>on</strong> methods, acyclic diene metathesis (ADMET)<br />
polyc<strong>on</strong>densati<strong>on</strong> is useful in the synthesis of a veriety of polymer architecures that would<br />
otherwise be difficult to obtain [4]. The main goal of this study is to describe the synthesis<br />
of unsaturated polyamides that can be obtained from plant oil derivatives via two different<br />
approaches. First, l<strong>on</strong>g chain aliphatic α,ω dienes with two symmetrically spaced amide<br />
segments were polymerized via ADMET polymerizati<strong>on</strong>. Sec<strong>on</strong>dly, E-dimethyl-eicos-10enedioate,<br />
a bio-b<strong>as</strong>ed unsaturated m<strong>on</strong>omer that w<strong>as</strong> obtained via metathesis <strong>and</strong> other<br />
reacti<strong>on</strong>s from c<strong>as</strong>tor oil, w<strong>as</strong> polymerized with different aliphatic diamines using str<strong>on</strong>g<br />
organic b<strong>as</strong>es, such <strong>as</strong> TBD, <strong>as</strong> catalysts. Both reacti<strong>on</strong> pathways led to PA X,20 <strong>and</strong> the<br />
two different routes were investigated, optimized <strong>and</strong> comapred to <strong>on</strong>e another. Moreover,<br />
the properties of the resulting polyamides were investigated revealing that these l<strong>on</strong>gchain<br />
polyamides are well applicable <strong>as</strong> engeneering pl<strong>as</strong>tics <strong>and</strong> that their properties<br />
depended <strong>on</strong> the structure of the applied m<strong>on</strong>omers, <strong>as</strong> expected. L<strong>as</strong>t, but not le<strong>as</strong>t our<br />
investigati<strong>on</strong>s led to new synthetic approaches that allow <strong>for</strong> the synthesis of ABA type<br />
polyamide block-copolymer with interesting applicati<strong>on</strong> possibilities.<br />

Though not total loss lubricants, hydraulic fluids have been cl<strong>as</strong>sified <strong>as</strong> “high risk loss”<br />
lubricants - they are used in large volumes in equipment that is susceptible to spills. The<br />
hydraulic fluids currently used in Latvia in wood harvesting <strong>and</strong> other envir<strong>on</strong>mentally<br />
sensitive are<strong>as</strong> still are mainly b<strong>as</strong>ed <strong>on</strong> mineral oils. Completely different is situati<strong>on</strong> in<br />
other EU countries, e.g., in Sweden, where the Swedish st<strong>and</strong>ard SS 155434 <strong>for</strong><br />
biodegradable hydraulic fluids is a legal requirement. There is an obvious need <strong>for</strong><br />
elaborati<strong>on</strong> of <strong>for</strong>mulati<strong>on</strong>s of hydraulic fluids b<strong>as</strong>ed <strong>on</strong> renewable natural resources in<br />
order to initiate <strong>and</strong> to promote producti<strong>on</strong> of such products in Latvia.<br />
Hydraulic fluids of harvesters should operate at temperature C <strong>and</strong> under high pressure<br />
(180-200 atm) till�C up to 70-100�range -25 change-over after 800-1200 operating hours.<br />
The main problems of biodegradable hydraulic fluids b<strong>as</strong>ed <strong>on</strong> vegetable oils are their low<br />
hydrolytic, thermal <strong>and</strong> oxidative stability, <strong>as</strong> well <strong>as</strong> bad low-temperature fluidity <strong>and</strong> shear<br />
stability.<br />
The biodegradable hydraulic fluids of harvesters available nowadays <strong>on</strong> market are much<br />
more expensive than their mineral oil b<strong>as</strong>ed analogues <strong>and</strong> often can not fulfill technical<br />
requirements set; due to this, new <strong>and</strong> cheaper technologies are developed using<br />
renewable b<strong>as</strong>e stocks. Investigati<strong>on</strong>s regarding new b<strong>as</strong>e fluids <strong>as</strong> well <strong>as</strong> new additives<br />
are very topical.<br />
We used rapeseed oil, its methyl- <strong>and</strong> ethylesters (RME <strong>and</strong> REE, corresp<strong>on</strong>dingly), byproducts<br />
of biodiesel producti<strong>on</strong> - mixture of free fatty acids, m<strong>on</strong>o- <strong>and</strong> diglycerides - <strong>as</strong><br />
raw materials <strong>for</strong> creati<strong>on</strong> of biodegradable hydraulic fluids. Following b<strong>as</strong>ic comp<strong>on</strong>ents<br />
<strong>for</strong> hydraulic fluids were synthesized:<br />
• Esters of fatty acids of rapeseed oil <strong>and</strong> polyols:<br />
o NPE - esters of neopentyl alcohol,<br />
o TMPE - esters of trimethylolpropane,<br />
o PEE - esters of pentaerythritol.<br />
• Estolides of rapeseed oil <strong>and</strong> their ethylhexylesters.<br />
Several derivatives of glycerol <strong>and</strong> fatty acids were prepared <strong>as</strong> potential additives <strong>for</strong><br />
improvement of technical parameters of new compositi<strong>on</strong>s:<br />
• Ethers of glycerol, obtained from:<br />
o glycerol <strong>and</strong> epoxydized rapeseed oil,<br />
o glycerol <strong>and</strong> mixture of epoxydized rapeseed oil fatty acids <strong>and</strong> m<strong>on</strong>o-, diglycerides<br />
(<strong>for</strong>med <strong>as</strong> a by-product in biodiesel producti<strong>on</strong>).<br />
• Polyhydroxycompounds, obtained from epoxydized RME.<br />
C, <strong>as</strong> well <strong>as</strong>�C <strong>and</strong> 100�We determined kinematic viscosity at 40 viscosity index, oxidative<br />
stability, cold-flow properties, acid value, foaming, air rele<strong>as</strong>e, fl<strong>as</strong>h point of elaborated<br />
compositi<strong>on</strong>s. The most of tested parameters corresp<strong>on</strong>ded to requirements, but low<br />
temperature fluidity after 7 days were unsatisfactory – additi<strong>on</strong> of temperature depressants<br />
(e.g., Lubrizol 7671A) improved this parameter. We used TBHQ <strong>as</strong> oxidati<strong>on</strong> inhibitor,<br />
Lubrizol 7671A <strong>as</strong> pour point depressor <strong>and</strong> polymethylsiloxane <strong>as</strong> antifoam agent in<br />
rapeseed oil b<strong>as</strong>ed <strong>for</strong>mulati<strong>on</strong>s.<br />

Biodiesel usually is produced by transesterificati<strong>on</strong> of various vegetable oils or animal fats<br />
with methanol. Un<strong>for</strong>tunately, methanol is highly toxic <strong>and</strong> harmful to human health.<br />
Applicati<strong>on</strong> of bioethanol instead of methanol would lead to more envir<strong>on</strong>mentally friendly<br />
producti<strong>on</strong> technology which almost completely would be b<strong>as</strong>ed <strong>on</strong> renewable resources.<br />
Currently in Europe there are no biodiesel producers using ethanol <strong>as</strong> a raw material,<br />
nevertheless FAEE (Fatty Acid Ethyl Esters) is used <strong>as</strong> biodiesel in Brazil. M<strong>and</strong>ate to<br />
CEN <strong>for</strong> st<strong>and</strong>ards <strong>for</strong> FAEE <strong>for</strong> use in diesel engines <strong>and</strong> heating fuels (M/393) w<strong>as</strong> set in<br />
2006.<br />
Previously we explored optimizati<strong>on</strong> of the synthesis of rapeseed oil ethyl esters (REE)<br />
using anhydrous ethanol <strong>and</strong> dehydrated ester-aldehyde fracti<strong>on</strong>s of ethanol rectificati<strong>on</strong><br />
[1]. We were interested to study possibilities of biodiesel preparati<strong>on</strong> from locally produced<br />
bioethanol. There<strong>for</strong>e our aim w<strong>as</strong> to establish optimal c<strong>on</strong>diti<strong>on</strong>s <strong>for</strong> synthesis of<br />
rapeseed oil ethyl esters (REE) by transesterificati<strong>on</strong> of oil with bioethanol produced by<br />
distillery “Jaunpag<strong>as</strong>ts Plus” from the local wheat. Experiments were carried out at room or<br />
higher (75-80oC) temperature; durati<strong>on</strong> of reacti<strong>on</strong> <strong>and</strong> amount of catalyst were varied.<br />
The best results were obtained when reacti<strong>on</strong> w<strong>as</strong> run 1 h at room temperature in the<br />
presence of 1.3-1.7% KOH catalyst (from oil m<strong>as</strong>s). When reacti<strong>on</strong> w<strong>as</strong> run at room<br />
temperature, yield of biodiesel reached just 71-82%. There<strong>for</strong>e we repeated the reacti<strong>on</strong>,<br />
adding catalyst-alcohol soluti<strong>on</strong> in two steps. The best result (yield of reacti<strong>on</strong> 97%) w<strong>as</strong><br />
reached, when total amount of added pot<strong>as</strong>sium hydroxide w<strong>as</strong> 1.5%.<br />
Sec<strong>on</strong>dly, we have established optimal c<strong>on</strong>diti<strong>on</strong>s <strong>for</strong> producti<strong>on</strong> of REE using<br />
ultr<strong>as</strong><strong>on</strong>icati<strong>on</strong>, <strong>as</strong> it is well known that ultr<strong>as</strong>ound <strong>as</strong>sisted transesterificati<strong>on</strong> of fatty acids<br />
proceed more quickly [2] allowing replacement of batch processing with c<strong>on</strong>tinuous flow<br />
processing <strong>and</strong> reducti<strong>on</strong> of investment <strong>and</strong> operati<strong>on</strong>al costs. Results of our experiments<br />
showed that durati<strong>on</strong> of reacti<strong>on</strong> can be reduced to 0.5 h - twice in comparis<strong>on</strong> with<br />
cl<strong>as</strong>sical method.<br />
Traditi<strong>on</strong>al workup process of REE with orthophosphoric acid <strong>and</strong> water lead to hardly<br />
separable emulsi<strong>on</strong>. There<strong>for</strong>e we applied Magnesol <strong>for</strong> purificati<strong>on</strong> of REE. Biodiesel<br />
treated with Magnesol corresp<strong>on</strong>ds to requirements of st<strong>and</strong>ard LVS EN 14214 <strong>and</strong> this<br />
method is simpler than workup with acid <strong>and</strong> water.<br />
We managed to prepare REE with 97% yield in two steps reacti<strong>on</strong> of rapeseed oil with<br />
bioethanol of local origin. Also we succeeded to reduce a durati<strong>on</strong> of reacti<strong>on</strong> by<br />
ultr<strong>as</strong><strong>on</strong>icati<strong>on</strong> (24 kHz) from 1 h to 0.5 h. Simplificati<strong>on</strong> of REE purificati<strong>on</strong> w<strong>as</strong> reached<br />
by applicati<strong>on</strong> of Magnesol. The technical parameters of our REE corresp<strong>on</strong>ded to<br />
requirements of LVS EN14214 set <strong>for</strong> biodiesel.<br />

BIOBASED SEGMENTED POLYURETHANES FROM METHYL OLEATE BASED<br />

In the polyurethane industry, c<strong>on</strong>venti<strong>on</strong>al polyether polyols are mostly produced from<br />
petroleum-b<strong>as</strong>ed alkylene oxides. Due to uncertainty about the future cost of petroleum, <strong>as</strong><br />
well <strong>as</strong> the desire to move toward more envir<strong>on</strong>mentally friendly feedstocks, many recent<br />
ef<strong>for</strong>ts have focused <strong>on</strong> replacing all or part of the c<strong>on</strong>venti<strong>on</strong>al petroleum-b<strong>as</strong>ed polyols<br />
with those made from renewable resources such <strong>as</strong> vegetable oils. In additi<strong>on</strong>, it is a<br />
challenge to use diisocyanates derived from aminoacids, making possible to produce<br />
polyurethanes completely from renewable resources. 1-3<br />
In this work we report the synthesis <strong>and</strong> characterizati<strong>on</strong> of polyether polyols from methyl<br />
oleate. The coordinative ring opening polymerisati<strong>on</strong> of epoxidized methyl oleate yields a<br />
linear polyether with Mn= 6.500 Da. The c<strong>on</strong>trolled reducti<strong>on</strong> of the carboxylate groups<br />
allows to obtain a set of polyether polyols with different primary hydroxyl c<strong>on</strong>tents.<br />
Depending <strong>on</strong> the degree of reducti<strong>on</strong> the polyols can have different properties <strong>and</strong>, when<br />
c<strong>on</strong>verted to polyurethanes, may impart different properties to the final product.<br />
These renewable polyols react with 4,4’-methylenebis(phenyl isocyanate) (MDI) or L-lysine<br />
diisocyante (LDI) to yield polyurethanes with different crosslinking density. Moreover, we<br />
carried out the reacti<strong>on</strong> of the polyetherpolyol with the isocyanates <strong>and</strong> 1,3-propanediol <strong>as</strong><br />
chain extender to obtain segmented polyurethanes with different hard segment c<strong>on</strong>tains.<br />
These materials were characterized by infrared spectroscopy (FTIR/ATR), differential<br />
scanning calorimetry (DSC), termogravimetric analysis (TGA) thermodynamomechanical<br />
analysis (DMTA), scanning electr<strong>on</strong> microscope (SEM) <strong>and</strong> X-Ray difracti<strong>on</strong>.<br />

DETAILED STUDIES OF SELF- AND CROSS-METATHESIS REACTIONS OF<br />
FATTY ACID METHYL ESTERS<br />

Self- <strong>and</strong> cross-metathesis[1] reacti<strong>on</strong>s with oleochemicals offer the potential to obtain<br />
value added chemical intermediates from plant oil renewable resources.[2,3] Here, the<br />
self-metathesis (SM) of methyl undec-10-enoate (1) <strong>as</strong> well <strong>as</strong> its cross-metathesis (CM)<br />
with methyl acrylate (MA) w<strong>as</strong> investigated in detail by systematically varying the applied<br />
reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s. The thus resulting unsaturated α,ω-diesters with a chainlength of 20<br />
<strong>and</strong> 11 carb<strong>on</strong> atoms, respectively, have a large potential from the synthesis of polyesters<br />
<strong>as</strong> well <strong>as</strong> polyamides from plant oil renewable resources.[4] Hence, four different<br />
metathesis catalysts were investigated under solvent-free c<strong>on</strong>diti<strong>on</strong>s at catalyst loadings<br />
ranging from 0.1 to 1 mol % <strong>and</strong> at temperatures ranging from 30 to 70 °C. All reacti<strong>on</strong>s<br />
were followed by GC <strong>and</strong>/or GC-MS in order to evaluate the c<strong>on</strong>versi<strong>on</strong> <strong>as</strong> well <strong>as</strong> the<br />
selectivity of the reacti<strong>on</strong>s. In the c<strong>as</strong>e of the SM reacti<strong>on</strong>s good to excellent c<strong>on</strong>versi<strong>on</strong>s<br />
were obtained with all catalysts, but the sec<strong>on</strong>d generati<strong>on</strong> metathesis catalysts revealed<br />
high amounts of olefin isomerisati<strong>on</strong> side-reacti<strong>on</strong>s.[5] In general, these SM reacti<strong>on</strong>s were<br />
highly reproducible, but at low catalyst loadings <strong>and</strong> low temperatures sometimes large<br />
variati<strong>on</strong>s in the observed c<strong>on</strong>versi<strong>on</strong>s were obtained. This w<strong>as</strong> not the c<strong>as</strong>e <strong>for</strong> the<br />
investigated CM reacti<strong>on</strong>s. Here, also good c<strong>on</strong>versi<strong>on</strong>s <strong>and</strong> CM yields were observed, if<br />
sec<strong>on</strong>d generati<strong>on</strong> metathesis catalysts were applied. Quite interestingly, these reacti<strong>on</strong>s<br />
showed a better reproducibility <strong>and</strong> the olefin isomerisati<strong>on</strong> of the also observed SM<br />
products w<strong>as</strong> almost completely suppressed. Moreover, due to these optimizati<strong>on</strong>s we<br />
were able to run these CM reacti<strong>on</strong>s with a 1:1 ratio of the reactants <strong>and</strong> low catalysts<br />
loadings, which is an improvement over described literature procedures.[3]<br />
Thus, in summary, we report <strong>on</strong> the detailed investigati<strong>on</strong> of the described SM <strong>as</strong> well <strong>as</strong><br />
CM reacti<strong>on</strong>s leading to new <strong>and</strong> optimized reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s <strong>for</strong> the producti<strong>on</strong>s of<br />
unsaturated α,ω-diester m<strong>on</strong>omers from renewable raw materials.<br />

Temperature dependant double b<strong>on</strong>d isomerizati<strong>on</strong> side reacti<strong>on</strong>s during ADMET<br />
polymerizati<strong>on</strong>s studied with a m<strong>on</strong>omer from renewable resources<br />

Acyclic diene metathesis (ADMET) polymerizati<strong>on</strong> h<strong>as</strong> developed into a very versatile<br />
technique <strong>for</strong> the preparati<strong>on</strong> of a variety of macromolecular architectures, including linear<br />
polymers [1,2], polymers with a defined degree of branching [3], telechelics <strong>as</strong> well <strong>as</strong><br />
block-copolymers [4,5]. Recently, the technique w<strong>as</strong> also applied to m<strong>on</strong>omers with a<br />
functi<strong>on</strong>ality > 2, thus resulting in hyperbranched macromolecules from AB2, AB3, <strong>and</strong> A3<br />
m<strong>on</strong>omers with B1 chainstoppers, respectively [6,7]. Applying this efficient catalytic<br />
process to m<strong>on</strong>omers from renewable resources will lead to the development of materials<br />
with interesting properties that have the potential to replace existing fossil oil b<strong>as</strong>ed<br />
materials [8].<br />
Within this c<strong>on</strong>tributi<strong>on</strong>, the utilizati<strong>on</strong> of plant oils <strong>as</strong> renewable raw materials <strong>for</strong><br />
m<strong>on</strong>omers <strong>and</strong> polymers will be discussed. There<strong>for</strong>e, the synthesis of a novel <strong>and</strong><br />
degradable m<strong>on</strong>omer from fatty acid derivatives will be described <strong>and</strong> its subsequent<br />
ADMET polymerizati<strong>on</strong> discussed in detail. We will focus our discussi<strong>on</strong>s <strong>on</strong> the<br />
investigati<strong>on</strong> of double-b<strong>on</strong>d isomerizati<strong>on</strong> side-reacti<strong>on</strong>s occurring during these ADMET<br />
polymerizati<strong>on</strong>s. There<strong>for</strong>e, the resulting polyesters were transesterified with methanol in<br />
order to investigate the nature <strong>and</strong> the amount of isomerizati<strong>on</strong> side-reacti<strong>on</strong>s that<br />
occurred during the polymerizati<strong>on</strong>s by GC-MS. These investigati<strong>on</strong>s revealed that the<br />
Grubbs first generati<strong>on</strong> catalyst does hardly show any side reacti<strong>on</strong>s up to a<br />
polymerizati<strong>on</strong> temperature of 90 °C, where<strong>as</strong> the sec<strong>on</strong>d generati<strong>on</strong> catalyst from Grubbs<br />
showed up to 75% isomerisati<strong>on</strong> side reacti<strong>on</strong>s depending <strong>on</strong> temperature <strong>as</strong> well <strong>as</strong> other<br />
polymerizati<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s. This study represents the first quantitative study of<br />
isomerisati<strong>on</strong> side reacti<strong>on</strong>s during ADMET polymerizati<strong>on</strong>s <strong>and</strong> will there<strong>for</strong>e help to tailor<br />
polymeric architectures prepared via this technique.<br />

Reducing the Envir<strong>on</strong>mental Impact of Olefin Metathesis Reacti<strong>on</strong>s<br />
Manuela Kniese, Michael A. R. Meier, University of Applied Sciences OOW, Emden,<br />
Germany; manuela.kniese@gmx.de<br />
As with most catalytic processes, olefin metathesis w<strong>as</strong> discovered by accident <strong>as</strong> a result<br />
of the study of Ziegler polymerizati<strong>on</strong>s with alternate metal systems.[1] The recent<br />
development of ruthenium olefin metathesis catalysts with high activity <strong>and</strong> functi<strong>on</strong>al<br />
group tolerance h<strong>as</strong> exp<strong>and</strong>ed the scope of this reacti<strong>on</strong> to synthesize organic compounds<br />
<strong>and</strong> to <strong>for</strong>m new C-C b<strong>on</strong>ds.[2,3] Many variants of this very useful <strong>and</strong> versatile reacti<strong>on</strong><br />
have been developed in the meantime including self-metathesis (SM), cross-metathesis<br />
(CM), ring-closing metathesis (RCM), ring-opening metathesis (ROM), ROM<br />
polymerizati<strong>on</strong> (ROMP) <strong>as</strong> well <strong>as</strong> acyclic diene metathesis polymerizati<strong>on</strong> (ADMET).[2,3]<br />
Within this project three reacti<strong>on</strong>s were investigated, which were suggested by the Nobel<br />
Prize laureate R. H. Grubbs <strong>as</strong> a useful, general <strong>and</strong> e<strong>as</strong>ily applicable plat<strong>for</strong>m <strong>for</strong> catalyst<br />
evaluati<strong>on</strong>: CM of allyl benzene with excess cis-1,4-diacetoxy-2-butene, CM of methyl<br />
acrylate with 5 hexenyl acetate <strong>and</strong> RCM of diethyldiallyl mal<strong>on</strong>ate.[4] As also typically<br />
described <strong>for</strong> other olefin metathesis reacti<strong>on</strong>s, these reacti<strong>on</strong>s were per<strong>for</strong>med in the<br />
organic solvent dichloromethane, which is toxic <strong>and</strong> envir<strong>on</strong>mentally unfriendly. Since the<br />
aim of this project is to optimize the reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s <strong>for</strong> these reacti<strong>on</strong>s <strong>and</strong> to avoid the<br />
use of toxic solvents, we studied these reacti<strong>on</strong>s in detail at different c<strong>on</strong>centrati<strong>on</strong>s in two<br />
solvents <strong>as</strong> well <strong>as</strong> in bulk. Dichloromethane <strong>and</strong> an envir<strong>on</strong>mentally friendly fatty acid<br />
derived solvent were used <strong>for</strong> comparis<strong>on</strong>. Our studies clearly showed that the menti<strong>on</strong>ed<br />
reacti<strong>on</strong>s can be per<strong>for</strong>med in bulk, thus completely avoiding organic solvents <strong>and</strong> thus<br />
highly reducing the envir<strong>on</strong>mental impact of such reacti<strong>on</strong>s. As a very positive side effect,<br />
the reacti<strong>on</strong>s in bulk usually required less catalyst <strong>and</strong> often provided better c<strong>on</strong>versi<strong>on</strong>s<br />
than their counterparts in organic solvent, most likely due to the higher c<strong>on</strong>centrati<strong>on</strong> of the<br />
reactants. Moreover, our studies also revealed that methyl esters of capric <strong>and</strong> lauric acid<br />
are suitable n<strong>on</strong>-toxic <strong>and</strong> thus envir<strong>on</strong>mentally friendly solvents <strong>for</strong> the investigated olefin<br />
metathesis reacti<strong>on</strong>s.<br />

In ages of depleting fossil reserves <strong>and</strong> incre<strong>as</strong>ing emissi<strong>on</strong> of green house g<strong>as</strong>es it is<br />
obvious that the utilizati<strong>on</strong> of renewable feedstocks is <strong>on</strong>e necessary step towards a<br />
sustainable development of our future. Especially plant derived oils bear a large potential<br />
<strong>for</strong> the substituti<strong>on</strong> of currently used petrochemicals, since a variety of value added<br />
chemical intermediates can be derived from these resources in a straight<strong>for</strong>ward f<strong>as</strong>hi<strong>on</strong><br />
taking full advantage of nature’s synthetic potential.<br />
Here, new approaches <strong>for</strong> the synthesis of m<strong>on</strong>omers from plant oils <strong>as</strong> renewable<br />
resources[1] via olefin metathesis[2,3] will be discussed. In particular, the synthesis of α,ωdifuncti<strong>on</strong>al<br />
chemical intermediates from renewable resources via the cross-metathesis<br />
reacti<strong>on</strong> of fatty acid methyl esters with allyl chloride is described.[4] Different ruthenium<br />
metathesis catalysts were investigated <strong>and</strong> the reacti<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s were optimized <strong>for</strong> high<br />
c<strong>on</strong>versi<strong>on</strong>s in combinati<strong>on</strong> with high cross-metathesis selectivity. New building blocks <strong>and</strong><br />
chemical intermediates from fatty acid derivates were thus obtained in catalytic reacti<strong>on</strong>s<br />
with low catalyst loadings under bulk c<strong>on</strong>diti<strong>on</strong>s. There<strong>for</strong>e, a new potential use of<br />
renewable raw materials <strong>for</strong> the synthesis of intermediates <strong>for</strong> Nyl<strong>on</strong>-11 <strong>and</strong> Nyl<strong>on</strong>-12 w<strong>as</strong><br />
dem<strong>on</strong>strated.<br />

The processing of textiles to achieve a particular h<strong>and</strong>le is <strong>on</strong>e of the most important<br />
<strong>as</strong>pects of finishing technology. Softeners <strong>and</strong> fatty acids improve soft h<strong>and</strong>le,<br />
smoothness, el<strong>as</strong>ticity, hydrophilic, antistatic <strong>and</strong> soil rele<strong>as</strong>e properties <strong>on</strong> textiles. Fatty<br />
acid amide derivatives are commercial textile softeners used to improve softness of fibers<br />
surface.<br />
In this research, cott<strong>on</strong> fabric w<strong>as</strong> used <strong>as</strong> substrate <strong>and</strong> it w<strong>as</strong> first scoured with n<strong>on</strong>i<strong>on</strong>ic<br />
detergent to remove any impurities. The fabric w<strong>as</strong> then treated with ani<strong>on</strong>ic, n<strong>on</strong>i<strong>on</strong>ic <strong>and</strong><br />
cati<strong>on</strong>ic fatty acid amide derivative softeners in water including 15 g/l at 30ºC <strong>for</strong> 30<br />
minutes using ultr<strong>as</strong><strong>on</strong>ic energy during treatment. The treated fabrics were then<br />
dried/cured at 130ºC <strong>for</strong> 40 sec<strong>on</strong>ds. Some of the physical properties of the fabrics treated<br />
under ultr<strong>as</strong>ound <strong>and</strong> those treated without ultr<strong>as</strong><strong>on</strong>ic energy, were compared <strong>and</strong><br />
discussed.<br />
As the results show, treatment of fabrics with softeners under ultr<strong>as</strong>ound is more effective<br />
compared to c<strong>on</strong>venti<strong>on</strong>al method.<br />

Nowadays, textile processing b<strong>as</strong>ed <strong>on</strong> biotechnology h<strong>as</strong> gained importance in view of<br />
stringent envir<strong>on</strong>mental <strong>and</strong> industrial safety c<strong>on</strong>diti<strong>on</strong>s. The best established applicati<strong>on</strong><br />
of biotechnology to textiles is the use of enzymes. These vital parts of all living organisms<br />
are organic catalysts with specific in the reacti<strong>on</strong> catalyzed <strong>and</strong> substrates selectivity.<br />
Traditi<strong>on</strong>al chemical treatments are replaced by enzymes because of their lower product<br />
quality, higher manufacturing cost, affecting some favorable bulk properties of textiles, not<br />
e<strong>as</strong>ily c<strong>on</strong>trolling, creating harsh c<strong>on</strong>diti<strong>on</strong>s, undesirable side effects <strong>and</strong>/or w<strong>as</strong>te disposal<br />
problems, more w<strong>as</strong>te, high odor process <strong>for</strong> workers <strong>and</strong> added energy c<strong>on</strong>sumpti<strong>on</strong> in<br />

Nyl<strong>on</strong> 6 fabrics were first treated with different c<strong>on</strong>centrati<strong>on</strong>s of subtilisin enzyme in<br />
aqueous soluti<strong>on</strong>s c<strong>on</strong>taining 1, 2, 4 <strong>and</strong> 6% <strong>for</strong> 80 min at 30ºC. The dyeing process w<strong>as</strong><br />
then carried out <strong>on</strong> the treated fabrics with disperse dye. A UV–Vis. spectrophotometer<br />
w<strong>as</strong> used <strong>for</strong> determinati<strong>on</strong> of dyebath exhausti<strong>on</strong>. Disperse dye showed higher<br />

The processing of textiles to achieve a particular h<strong>and</strong>le is <strong>on</strong>e of the most important<br />
<strong>as</strong>pects of finishing technology. Softeners are <strong>on</strong>e of the main compounds in finishing<br />

PIBOLEO project: Eco Innovative process <strong>for</strong> multi-functi<strong>on</strong>al bi-oleothermal<br />
treatment <strong>for</strong> wood preservati<strong>on</strong> <strong>and</strong> fire proofing<br />

Although they are usually quite effective, typical wood treatments are not necessarily very<br />
envir<strong>on</strong>ment-friendly, in terms of the treatment itself <strong>and</strong> of the active substances used<br />
(flame retardants, biocides). In this day <strong>and</strong> age, <strong>as</strong> the ecological <strong>as</strong>pects are becoming<br />
more <strong>and</strong> more important, many research projects aim at improving wood treatment in an<br />
envir<strong>on</strong>ment-friendly manner.<br />
In France a simple bi-oleothermal© process h<strong>as</strong> been developed by CIRAD <strong>and</strong> FCBA in<br />
order to make the treated wood more stable <strong>and</strong> less sensitive when used outdoors. The<br />
interest of this now well m<strong>as</strong>tered alternative method <strong>for</strong> wood protecti<strong>on</strong> is to allow wood<br />
drying <strong>as</strong> well <strong>as</strong> wood treatment in a single process. This two stage process operates at<br />
atmospheric pressure <strong>and</strong> uses two hot oil baths. Nevertheless, the <strong>for</strong>mulati<strong>on</strong> of the oils<br />
used needs major improvement in order to adapt the per<strong>for</strong>mances of the treated wooden<br />
material (durability towards wood destroying organisms, fireproofing, etc...) to its end-use.<br />
The improvement of this bi-oleothermal wood treatment is the subject of the PIBOLEO<br />
project, which is supported by the French Nati<strong>on</strong>al Agency <strong>for</strong> Research (ANR - ADEME).<br />
This project is currently in its early stages <strong>and</strong> focuses <strong>for</strong> now <strong>on</strong> the optimizati<strong>on</strong> of the<br />
compositi<strong>on</strong> of the sec<strong>on</strong>d bath, which is the <strong>on</strong>e c<strong>on</strong>taining the active substances.<br />
The nature of the sec<strong>on</strong>d bath depends a lot <strong>on</strong> the active substances used <strong>for</strong> improving<br />
the fire, fungus or insect resistance of the treated wood. If these substances are not<br />
miscible with oil but soluble in water, it is then necessary to develop an emulsi<strong>on</strong><br />
c<strong>on</strong>taining enough of each of the substances to impart the desired properties to the treated<br />
wood. In that c<strong>as</strong>e, the use of surfactants is required. There<strong>for</strong>e, a major axis of the<br />
PIBOLEO h<strong>as</strong> been to optimize the surfactant systems in these water-in-oil (W/O)<br />
emulsi<strong>on</strong>s. It is quite challenging to design emulsi<strong>on</strong>s that can withst<strong>and</strong> the thermal<br />
shocks <strong>and</strong> the additi<strong>on</strong> of impurities coming from the wood (water, sap, etc.) <strong>as</strong>sociated<br />
with the treatment without deph<strong>as</strong>ing.<br />
In the c<strong>as</strong>e of active substances that are not soluble in oil, chemical modificati<strong>on</strong> <strong>and</strong><br />
grafting of those substances <strong>on</strong>to oil can be an alternative opti<strong>on</strong>. They can then become<br />
soluble in oil without losing their properties <strong>as</strong> fire retardants or biocides. Several synthesis<br />
routes are currently under investigati<strong>on</strong> in the PIBOLEO project. In that c<strong>as</strong>e or if the<br />
active substances are naturally soluble in oil, there is no need to add water in the sec<strong>on</strong>d<br />
bath <strong>and</strong> a simple <strong>for</strong>mulati<strong>on</strong> of the oil is sufficient. The stability of the bath is then<br />
improved (the <strong>on</strong>ly c<strong>on</strong>cern is the oxidative stability of the oil <strong>and</strong> the active substances<br />
since deph<strong>as</strong>ing is not a possibility).

present promising route <strong>for</strong> sec<strong>on</strong>d generati<strong>on</strong> biofuels. The catalytic activity of comm<strong>on</strong><br />
cellul<strong>as</strong>es is well known i.e. optimal pH, temperature, etc [2]. Many possible substrates<br />
were also already tested [3]. However, <strong>on</strong>ly little work, at our knowledge, w<strong>as</strong> d<strong>on</strong>e <strong>on</strong><br />
cellul<strong>as</strong>es activity in n<strong>on</strong>-aqueous media [4].<br />
We present here a study of enzymatic activity of three different commercial cellul<strong>as</strong>es from<br />
A. niger, Aspergillus sp. <strong>and</strong> Trichoderma virens in various biph<strong>as</strong>ic, organic solvent /<br />
buffer, c<strong>on</strong>diti<strong>on</strong>s.<br />
We found that the A. niger cellul<strong>as</strong>es had the best catalytic activity in a biph<strong>as</strong>ic media<br />
c<strong>on</strong>taining up to 75 % of chloro<strong>for</strong>m ph<strong>as</strong>e. In this c<strong>as</strong>e up to 40 g/L cellulose c<strong>on</strong>tained in<br />
buffer ph<strong>as</strong>e can be trans<strong>for</strong>med in 4 hours by 10 g/L overall enzyme.<br />
